Pull networking updates from David Miller:

 1) Platform regulatory domain support for ath10k, from Bartosz
    Markowski.

 2) Centralize min/max MTU checking, thus removing tons of duplicated
    code all of the the various drivers. From Jarod Wilson.

 3) Support ingress actions in act_mirred, from Shmulik Ladkani.

 4) Improve device adjacency tracking, from David Ahern.

 5) Add support for LED triggers on PHY link state changes, from Zach
    Brown.

 6) Improve UDP socket memory accounting, from Paolo Abeni.

 7) Set SK_MEM_QUANTUM to a fixed size of 4096, instead of PAGE_SIZE.
    From Eric Dumazet.

 8) Collapse TCP SKBs at retransmit time even if the right side SKB has
    frags. Also from Eric Dumazet.

 9) Add IP_RECVFRAGSIZE and IPV6_RECVFRAGSIZE cmsgs, from Willem de
    Bruijn.

10) Support routing by UID, from Lorenzo Colitti.

11) Handle L3 domain binding (ie. VRF) for RAW sockets, from David
    Ahern.

12) tcp_get_info() can run lockless, from Eric Dumazet.

13) 4-tuple UDP hashing in SFC driver, from Edward Cree.

14) Avoid reorders in GRO code, from Eric Dumazet.

15) IPV6 Segment Routing support, from David Lebrun.

16) Support MPLS push and pop for L3 packets in openvswitch, from Jiri
    Benc.

17) Add LRU datastructure support for BPF, Martin KaFai Lau.

18) VF support in liquidio driver, from Raghu Vatsavayi.

19) Multiqueue support in alx driver, from Tobias Regnery.

20) Networking cgroup BPF support, from Daniel Mack.

21) TCP chronograph measurements, from Francis Yan.

22) XDP support for qed driver, from Yuval Mintz.

23) BPF based lwtunnels, from Thomas Graf.

24) Consistent FIB dumping to offloading drivers, from Ido Schimmel.

25) Many optimizations for UDP under high load, from Eric Dumazet.
