Merge tag 'net-6.5-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  No known outstanding regressions.

  Fixes to fixes:

   - virtio-net: set queues after driver_ok, avoid a potential race
     added by recent fix

   - Revert "vlan: Fix VLAN 0 memory leak", it may lead to a warning
     when VLAN 0 is registered explicitly

   - nf_tables:
      - fix false-positive lockdep splat in recent fixes
      - don't fail inserts if duplicate has expired (fix test failures)
      - fix races between garbage collection and netns dismantle

  Current release - new code bugs:

   - mlx5: Fix mlx5_cmd_update_root_ft() error flow

  Previous releases - regressions:

   - phy: fix IRQ-based wake-on-lan over hibernate / power off

  Previous releases - always broken:

   - sock: fix misuse of sk_under_memory_pressure() preventing system
     from exiting global TCP memory pressure if a single cgroup is under
     pressure

   - fix the RTO timer retransmitting skb every 1ms if linear option is
     enabled

   - af_key: fix sadb_x_filter validation, amment netlink policy

   - ipsec: fix slab-use-after-free in decode_session6()

   - macb: in ZynqMP resume always configure PS GTR for non-wakeup
     source

  Misc:

   - netfilter: set default timeout to 3 secs for sctp shutdown send and
     recv state (from 300ms), align with protocol timers"
