Merge tag 'net-6.3-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from netfilter, wifi and ipsec.

  A little more changes than usual, but it's pretty normal for us that
  the rc3/rc4 PRs are oversized as people start testing in earnest.

  Possibly an extra boost from people deploying the 6.1 LTS but that's
  more of an unscientific hunch.

  Current release - regressions:

   - phy: mscc: fix deadlock in phy_ethtool_{get,set}_wol()

   - virtio: vsock: don't use skbuff state to account credit

   - virtio: vsock: don't drop skbuff on copy failure

   - virtio_net: fix page_to_skb() miscalculating the memory size

  Current release - new code bugs:

   - eth: correct xdp_features after device reconfig

   - wifi: nl80211: fix the puncturing bitmap policy

   - net/mlx5e: flower:
      - fix raw counter initialization
      - fix missing error code
      - fix cloned flow attribute

   - ipa:
      - fix some register validity checks
      - fix a surprising number of bad offsets
      - kill FILT_ROUT_CACHE_CFG IPA register

  Previous releases - regressions:

   - tcp: fix bind() conflict check for dual-stack wildcard address

   - veth: fix use after free in XDP_REDIRECT when skb headroom is small

   - ipv4: fix incorrect table ID in IOCTL path

   - ipvlan: make skb->skb_iif track skb->dev for l3s mode

   - mptcp:
      - fix possible deadlock in subflow_error_report
      - fix UaFs when destroying unaccepted and listening sockets

   - dsa: mv88e6xxx: fix max_mtu of 1492 on 6165, 6191, 6220, 6250, 6290

  Previous releases - always broken:

   - tcp: tcp_make_synack() can be called from process context, don't
     assume preemption is disabled when updating stats

   - netfilter: correct length for loading protocol registers

   - virtio_net: add checking sq is full inside xdp xmit

   - bonding: restore IFF_MASTER/SLAVE flags on bond enslave Ethertype
     change

   - phy: nxp-c45-tja11xx: fix MII_BASIC_CONFIG_REV bit number

   - eth: i40e: fix crash during reboot when adapter is in recovery mode

   - eth: ice: avoid deadlock on rtnl lock when auxiliary device
     plug/unplug meets bonding

   - dsa: mt7530:
      - remove now incorrect comment regarding port 5
      - set PLL frequency and trgmii only when trgmii is used

   - eth: mtk_eth_soc: reset PCS state when changing interface types

  Misc:

   - ynl: another license adjustment

   - move the TCA_EXT_WARN_MSG attribute for tc action"
