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"
