Networking fixes for 5.16-final, including fixes from bpf, and WiFi.
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()
