After discovering that wide use of prefetch on modern CPUs

them an explicit include via the following $0.02 script.

This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.
For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.
All drivers compiled with make allyesconfig ion x86_64 have been
updated.

Without calling of netif_carrier_off at the end of the probe the operstate
is unknown when the device is initially opened. By default the carrier is
on so when the device is opened and netif_carrier_on is called the link
watch event is not fired and operstate remains zero (unknown).

The forcedeth driver uses the legacy PCI power management, so it has
to do PCI-specific things in its ->suspend() and ->resume() callbacks
and some of them are not done correctly.
Convert forcedeth to the new PCI power management framework and make
it let the PCI subsystem take care of all the PCI-specific aspects of
device handling during system power transitions.

Many (but not all) drivers check to see whether there is a vlan
group configured before using a tag stored in the skb. There's
not much point in this check since it just throws away data that
should only be present in the expected circumstances. However,
it will soon be legal and expected to get a vlan tag when no
vlan group is configured, so remove this check from all drivers
to avoid dropping the tags.

The macros for the values of the bit field describing the four
different versions of statistics supported by different hardware
variants were being misused. Where the code was trying to test if the
hardware implements V3, it was actually testing whether it implements
any of V1, V2, or V3, causing the driver to report statistics that
don't really exist in the hardware, with bogus values.

All distributions enable it, therefore no significant body of users
are even testing the driver with it disabled. And making NAPI
configurable is heavily discouraged anyways.
I left the MSI-X interrupt enabling thing in an "#if 0" block
so hopefully someone can debug that and it can get re-enabled.
Probably it was just one of the NVIDIA chipset MSI erratas that
we work handle these days in the PCI quirks (see drivers/pci/quirks.c

implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Add a phy_power_down parameter to forcedeth: set to 1 to power down the
phy and disable the link when an interface goes down; set to 0 to always
leave the phy powered up.
The phy power state persists across reboots; Windows, some BIOSes, and
older versions of Linux don't bother to power up the phy again, forcing
users to remove all power to get the interface working (see
http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy
powered on is the safest default behavior. Users accustomed to seeing
the link state reflect the interface state and/or wanting to minimize
power consumption can set phy_power_down=1 if compatibility with other
OSes is not an issue.

This patch clears the irqstatus register with the exact same events it
has read from it. Since the read-write operation is not atomic, a new
irqstatus bit could have been set in between these operations and would
then be cleared accidentally.
Secondly, we now don't need any spin lock protection when
scheduling/completing napi poll as the isr will not execute anymore (as
we turn off all interrupts now).

This patch adds the logic to moderate the interrupts by changing the
mode between throughput and poll. If there has been a large amount of
time without any burst of network load, the code will transition to pure
throughput mode (where each tx/rx/other will cause an interrupt). If
bursts of network load occurs, it will transition to poll based mode to
help reduce cpu utilization (it will not interrupt on each packet) while
maintaining the optimum network bandwidth utilization.

Commit f55c21fd9a92a444e55ad1ca4e4732d56661bf2e ("forcedeth: call
restore mac addr in nv_shutdown path"), which was introduced to fix
the regression tracked at
http://bugzilla.kernel.org/show_bug.cgi?id=11358 causes the
wake-on-lan mac to be reversed in the shutdown path. Apparently the
forcedeth situation is rather messy in that the mac we need to
writeback for a subsequent modprobe to work is exactly the reverse of
what is needed for proper wake-on-lan.
The following patch explains the situation in the comments and
makes the call to nv_restore_mac_addr() conditional (only called if
we are not really going for poweroff).

Bring the physical link down when the interface is down by placing the PHY
in power-down state, unless WOL is enabled. This mirrors the behavior of
other drivers including e1000 and tg3.
Without the patch, ifconfig down leaves the physical link up, which confuses
datacenter users who expect the link lights both on the NIC and the switch to
go out when they bring an interface down.
Furthermore, even though the phy is powered on, autonegotiation stops working,
so a normally gigabit link might suddenly become 100 Mbit half-duplex when the
interface goes down, and become gigabit when it comes up again.
Ayaz said:
I would not include this patch until further testing is performed. NVIDIA
MCP chips use 3rd party PHY vendors. By powering down the phy, it could
have adverse affects on certain phys.

This eliminates the following often-generated warning from my 64 bit
Opteron SMP test stand:
eth0: too many iterations (6) in nv_nic_irq
According to the web, the problem is that the forcedeth driver has a
too-low value for max_interrupt_work. Grepping the kernel I see that
forcedeth has the second lowest value of all ethernet drivers (ie, 6).
Most are in the 20-40 range. So this patch increases this a bit, from 6
to 15 (at 15 forcedeth becomes the driver with third-lowest
max_interrupt_work value).
My test stand, which used to print out the above warnings repetitively
whenever it was under heavy net load, no longer does so.

adapters integrated into the NVidia MCP55 chipsets fail to work in kexeced

Fix the checksum feature advertised in device flags. The hardware support
TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers).
However, the kernel feature flags do not distinguish IPv6 with/without
extension headers.
Therefore, the driver needs to use NETIF_F_IP_CSUM instead of
NETIF_F_HW_CSUM since the latter includes all IPv6 packets.
A future patch can be created to check for extension headers and perform

This is caused by the following snippet in nv_set_settings:
netif_carrier_off(dev);
if (netif_running(dev)) {
nv_disable_irq(dev);
netif_tx_lock_bh(dev);
spin_lock(&np->lock);
/* stop engines */
nv_stop_rxtx(dev);
spin_unlock(&np->lock);
netif_tx_unlock_bh(dev);
}
Because of nv_disable_irq this is probably not really a problem
though (I guess) and replacing the spin_lock with spin_lock_irqsave
could keep interrupts disabled for a longer period of time because
of delays in nv_stop_rx and nv_stop_tx.

We currently don't signal the kernel we that this device can wake
the system. Call device_init_wakeup() to correct this.
Without this device_can_wakeup and device_may_wakeup will return
incorrect values.
Together with the minimized acpi wakeup patch (6/4 ;)), which will
follow in the next mail, this really makes wake-on-lan work for me

This critical patch fixes a mac address issue recently introduced. If the
device's mac address was in correct order and the flag
NVREG_TRANSMITPOLL_MAC_ADDR_REV was set, during nv_remove the flag would get
cleared. During next load, the mac address would get reversed because the
flag is missing.
As it has been indicated previously, the flag is cleared across a low power
transition. Therefore, the driver should set the mac address back into the
reversed order when clearing the flag.
Also, the driver should set back the flag after a low power transition to
protect against kexec command calling nv_probe a second time.

The driver should inform the stack when checksum has been performed by
the HW when both IP and TCP (or UDP) checksum flags are indicated by HW.
Previously, it would also inform the stack when only IP checksum flag
was indicated by HW. This can cause data corruption when IP fragments
are used. The IP Identification field can wrap around and cause data
from new fragments to fill into older fragment slots with same IP Id.
The stack would then not perform TCP/UDP checksum (after re-assembly of
all fragments) since driver falsely stated it was already calculated.

For cards that initially have the MAC address stored in reverse order,
the forcedeth driver uses a flag to signal whether the address was
already corrected, so that it is not reversed again on a subsequent
probe.
Unfortunately this flag, which is stored in a register of the card,
seems to get lost during suspend, resulting in the MAC address being
reversed again. To fix that, the MAC address needs to be written back
in reversed order before we suspend and the flag needs to be reset.
The flag is still required because at least kexec will never write
back the reversed address and thus needs to know what state the card
is in.

* don't bother to print error message when pci_enable_device() fails,
it will do so for us.
* use dev_printk() rather than printk() in nv_probe(). This gives
use a standardized output similar to the rest of the kernel, and
eliminates the need to manually print out PCI bus id.
* use DRV_NAME constant where appropriate

For the operations
get-tx-csum
get-sg
get-tso
get-ufo
the default ethtool_op_xxx behavior is fine for all drivers, so we
permit op==NULL to imply the default behavior.
This provides a more uniform behavior across all drivers, eliminating
ethtool(8) "ioctl not supported" errors on older drivers that had
not been updated for the latest sub-ioctls.
The ethtool_op_xxx() functions are left exported, in case anyone
wishes to call them directly from a driver-private implementation --
a not-uncommon case. Should an ethtool_op_xxx() helper remain unused
for a while, except by net/core/ethtool.c, we can un-export it at a

Several devices have multiple independant RX queues per net
device, and some have a single interrupt doorbell for several
queues.
In either case, it's easier to support layouts like that if the
structure representing the poll is independant from the net
device itself.
The signature of the ->poll() call back goes from:
int foo_poll(struct net_device *dev, int *budget)
to
int foo_poll(struct napi_struct *napi, int budget)
The caller is returned the number of RX packets processed (or
the number of "NAPI credits" consumed if you want to get
abstract). The callee no longer messes around bumping
dev->quota, *budget, etc. because that is all handled in the
caller upon return.
The napi_struct is to be embedded in the device driver private data
structures.
Furthermore, it is the driver's responsibility to disable all NAPI
instances in it's ->stop() device close handler. Since the
napi_struct is privatized into the driver's private data structures,
only the driver knows how to get at all of the napi_struct instances
it may have per-device.

Michael Chan, Jeff Garzik, and Jamal Hadi Salim.

If the forcedeth driver receives too much work in an interrupt, it
assumes it has a broken hardware with stuck IRQ. It works around the
problem by disabling interrupts on the nic but makes a printk while
holding device spinlog - which isn't smart thing to do if you have
netconsole on the same nic.
This patch moves the printk's out of the spinlock protected area.
Without this patch the machine hangs hard. With this patch everything
still works even when there is significant increase on CPU usage while
using the nic.

All drivers implement ethtool get_perm_addr the same way -- by calling

caller and avoid going through the drivers.

In older chipsets, the mac address was stored in reversed order.
However, in newer chipsets, the mac address is in correct order. This
patch takes those newer chipsets into account and does not rely on a

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.
Compile tested with make all{yes,mod}config on x86_64 and i386.

I happened to notice that a system with an NVidia NIC using the
forcedeth driver won't wake-on-LAN if the interface was in promiscuous
mode when you power off. By experiment, it looks like
the hardware needs to have NvRegPacketFilterFlags set to
NVREG_PFF_ALWAYS|NVREG_PFF_MYADDR (i.e., receive unicast packets to my
address) in order for WoL to work.

Many drivers had code that did kill_vid, but they weren't doing vlan
filtering. With new API the stub is unneeded unless device sets
NETIF_F_HW_VLAN_FILTER.

in acenic, and forcedeth.
