Merge tag 'net-6.4-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Selftests excluded - we have 58 patches and diff of +442/-199, which
  isn't really small but perhaps with the exception of the WiFi locking
  change it's old(ish) bugs.

  We have no known problems with v6.4.

  The selftest changes are rather large as MPTCP folks try to apply
  Greg's guidance that selftest from torvalds/linux should be able to
  run against stable kernels.

  Last thing I should call out is the DCCP/UDP-lite deprecation notices.
  We are fairly sure those are dead, but if we're wrong reverting them
  back in won't be fun.

  Current release - regressions:

   - wifi:
      - cfg80211: fix double lock bug in reg_wdev_chan_valid()
      - iwlwifi: mvm: spin_lock_bh() to fix lockdep regression

  Current release - new code bugs:

   - handshake: remove fput() that causes use-after-free

  Previous releases - regressions:

   - sched: cls_u32: fix reference counter leak leading to overflow

   - sched: cls_api: fix lockup on flushing explicitly created chain

  Previous releases - always broken:

   - nf_tables: integrate pipapo into commit protocol

   - nf_tables: incorrect error path handling with NFT_MSG_NEWRULE, fix
     dangling pointer on failure

   - ping6: fix send to link-local addresses with VRF

   - sched: act_pedit: parse L3 header for L4 offset, the skb may not
     have the offset saved

   - sched: act_ct: fix promotion of offloaded unreplied tuple

   - sched: refuse to destroy an ingress and clsact Qdiscs if there are
     lockless change operations in flight

   - wifi: mac80211: fix handful of bugs in multi-link operation

   - ipvlan: fix bound dev checking for IPv6 l3s mode

   - eth: enetc: correct the indexes of highest and 2nd highest TCs

   - eth: ice: fix XDP memory leak when NIC is brought up and down

  Misc:

   - add deprecation notices for UDP-lite and DCCP

   - selftests: mptcp: skip tests not supported by old kernels

   - sctp: handle invalid error codes without calling BUG()"
