Merge tag 'net-5.16-final' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski"
 "Networking fixes, including fixes from bpf, and WiFi. One last pull
  request, turns out some of the recent fixes did more harm than good.

  Current release - regressions:

   - Revert "xsk: Do not sleep in poll() when need_wakeup set", made the
     problem worse

   - Revert "net: phy: fixed_phy: Fix NULL vs IS_ERR() checking in
     __fixed_phy_register", broke EPROBE_DEFER handling

   - Revert "net: usb: r8152: Add MAC pass-through support for more
     Lenovo Docks", broke setups without a Lenovo dock

  Current release - new code bugs:

   - selftests: set amt.sh executable

  Previous releases - regressions:

   - batman-adv: mcast: don't send link-local multicast to mcast routers

  Previous releases - always broken:

   - ipv4/ipv6: check attribute length for RTA_FLOW / RTA_GATEWAY

   - sctp: hold endpoint before calling cb in
     sctp_transport_lookup_process

   - mac80211: mesh: embed mesh_paths and mpp_paths into
     ieee80211_if_mesh to avoid complicated handling of sub-object
     allocation failures

   - seg6: fix traceroute in the presence of SRv6

   - tipc: fix a kernel-infoleak in __tipc_sendmsg()"
