Merge tag 'net-5.19-final' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bluetooth and netfilter, no known blockers for
  the release.

  Current release - regressions:

   - wifi: mac80211: do not abuse fq.lock in ieee80211_do_stop(), fix
     taking the lock before its initialized

   - Bluetooth: mgmt: fix double free on error path

  Current release - new code bugs:

   - eth: ice: fix tunnel checksum offload with fragmented traffic

  Previous releases - regressions:

   - tcp: md5: fix IPv4-mapped support after refactoring, don't take the
     pure v6 path

   - Revert "tcp: change pingpong threshold to 3", improving detection
     of interactive sessions

   - mld: fix netdev refcount leak in mld_{query | report}_work() due to
     a race

   - Bluetooth:
      - always set event mask on suspend, avoid early wake ups
      - L2CAP: fix use-after-free caused by l2cap_chan_put

   - bridge: do not send empty IFLA_AF_SPEC attribute

  Previous releases - always broken:

   - ping6: fix memleak in ipv6_renew_options()

   - sctp: prevent null-deref caused by over-eager error paths

   - virtio-net: fix the race between refill work and close, resulting
     in NAPI scheduled after close and a BUG()

   - macsec:
      - fix three netlink parsing bugs
      - avoid breaking the device state on invalid change requests
      - fix a memleak in another error path

  Misc:

   - dt-bindings: net: ethernet-controller: rework 'fixed-link' schema

   - two more batches of sysctl data race adornment"
