1. 16 VLAN ID rules
2. 16 L2 EtherType rules
3. 8 L3/L4 5-Tuple rules
The driver utilizes the ethtool interface for configuring ntuple filters,
via ``ethtool -N ``.
To enable or disable the RX flow rules::
ethtool -K ethX ntuple
When disabling ntuple filters, all the user programmed filters are
flushed from the driver cache and hardware. All needed filters must
be re-added when ntuple is re-enabled.
Because of the fixed order of the rules, the location of filters is also fixed:
- Locations 0 - 15 for VLAN ID filters
- Locations 16 - 31 for L2 EtherType filters
- Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)
The L3/L4 5-tuple (protocol, source and destination IP address, source and
destination TCP/UDP/SCTP port) is compared against 8 filters. For IPv4, up to
8 source and destination addresses can be matched. For IPv6, up to 2 pairs of
addresses can be supported. Source and destination ports are only compared for
TCP/UDP/SCTP packets.
To add a filter that directs packet to queue 5, use
``<-N|-U|--config-nfc|--config-ntuple>`` switch::
ethtool -N flow-type udp4 src-ip 10.0.0.1 dst-ip 10.0.0.2 src-port 2000 dst-port 2001 action 5
- action is the queue number.
- loc is the rule number.
For ``flow-type ip4|udp4|tcp4|sctp4|ip6|udp6|tcp6|sctp6`` you must set the loc
number within 32 - 39.
For ``flow-type ip4|udp4|tcp4|sctp4|ip6|udp6|tcp6|sctp6`` you can set 8 rules
for traffic IPv4 or you can set 2 rules for traffic IPv6. Loc number traffic
IPv6 is 32 and 36.
At the moment you can not use IPv4 and IPv6 filters at the same time.
Example filter for IPv6 filter traffic::
sudo ethtool -N flow-type tcp6 src-ip 2001:db8:0:f101::1 dst-ip 2001:db8:0:f101::2 action 1 loc 32
sudo ethtool -N flow-type ip6 src-ip 2001:db8:0:f101::2 dst-ip 2001:db8:0:f101::5 action -1 loc 36
Example filter for IPv4 filter traffic::
sudo ethtool -N flow-type udp4 src-ip 10.0.0.4 dst-ip 10.0.0.7 src-port 2000 dst-port 2001 loc 32
sudo ethtool -N flow-type tcp4 src-ip 10.0.0.3 dst-ip 10.0.0.9 src-port 2000 dst-port 2001 loc 33
sudo ethtool -N flow-type ip4 src-ip 10.0.0.6 dst-ip 10.0.0.4 loc 34
If you set action -1, then all traffic corresponding to the filter will be discarded.
The maximum value action is 31.
The VLAN filter (VLAN id) is compared against 16 filters.
VLAN id must be accompanied by mask 0xF000. That is to distinguish VLAN filter
from L2 Ethertype filter with UserPriority since both User Priority and VLAN ID
are passed in the same 'vlan' parameter.
To add a filter that directs packets from VLAN 2001 to queue 5::
ethtool -N flow-type ip4 vlan 2001 m 0xF000 action 1 loc 0
L2 EtherType filters allows filter packet by EtherType field or both EtherType
and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That is to
distinguish VLAN filter from L2 Ethertype filter with UserPriority since both
User Priority and VLAN ID are passed in the same 'vlan' parameter.
To add a filter that directs IP4 packess of priority 3 to queue 3::
ethtool -N flow-type ether proto 0x800 vlan 0x600 m 0x1FFF action 3 loc 16
To see the list of filters currently present::
ethtool <-u|-n|--show-nfc|--show-ntuple>
Rules may be deleted from the table itself. This is done using::
sudo ethtool <-N|-U|--config-nfc|--config-ntuple> delete
- loc is the rule number to be deleted.
Rx filters is an interface to load the filter table that funnels all flow
into queue 0 unless an alternative queue is specified using "action". In that
case, any flow that matches the filter criteria will be directed to the
appropriate queue. RX filters is supported on all kernels 2.6.30 and later.
