Merge tag 'net-6.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni:
"Including fixes from bpf and wifi.
Current release - regressions:
- neighbour: fix __randomize_layout crash in struct neighbour
- r8169: fix deadlock on RTL8125 in jumbo mtu mode
Previous releases - regressions:
- wifi:
- mac80211: fix warning at station removal time
- cfg80211: fix CQM for non-range use
- tools: ynl-gen: fix unexpected response handling
- octeontx2-af: fix possible buffer overflow
- dpaa2: recycle the RX buffer only after all processing done
- rswitch: fix missing dev_kfree_skb_any() in error path
Previous releases - always broken:
- ipv4: fix uaf issue when receiving igmp query packet
- wifi: mac80211: fix debugfs deadlock at device removal time
- bpf:
- sockmap: af_unix stream sockets need to hold ref for pair sock
- netdevsim: don't accept device bound programs
- selftests: fix a char signedness issue
- dsa: mv88e6xxx: fix marvell 6350 probe crash
- octeontx2-pf: restore TC ingress police rules when interface is up
- wangxun: fix memory leak on msix entry
- ravb: keep reverse order of operations in ravb_remove()"
