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()"
