Merge tag 'net-6.4-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from ipsec, bpf, mptcp and netfilter.

  Current release - regressions:

   - netfilter: add NFT_TRANS_PREPARE_ERROR to deal with bound set/chain

   - eth: mlx5e:
      - fix scheduling of IPsec ASO query while in atomic
      - free IRQ rmap and notifier on kernel shutdown

  Current release - new code bugs:

   - phy: manual remove LEDs to ensure correct ordering

  Previous releases - regressions:

   - mptcp: fix possible divide by zero in recvmsg()

   - dsa: revert "net: phy: dp83867: perform soft reset and retain
     established link"

  Previous releases - always broken:

   - sched: netem: acquire qdisc lock in netem_change()

   - bpf:
      - fix verifier id tracking of scalars on spill
      - fix NULL dereference on exceptions
      - accept function names that contain dots

   - netfilter: disallow element updates of bound anonymous sets

   - mptcp: ensure listener is unhashed before updating the sk status

   - xfrm:
      - add missed call to delete offloaded policies
      - fix inbound ipv4/udp/esp packets to UDPv6 dualstack sockets

   - selftests: fixes for FIPS mode

   - dsa: mt7530: fix multiple CPU ports, BPDU and LLDP handling

   - eth: sfc: use budget for TX completions

  Misc:

   - wifi: iwlwifi: add support for SO-F device with PCI id 0x7AF0"
