Pull networking fixes from David Miller:
 "A quick batch of fixes, including the annoying bad lock stack problem
  introduced by udp_sk_rx_dst_set() locking change:

   1) Use xchg() instead of sk_dst_lock() in udp_sk_rx_dst_set(), from
      Eric Dumazet.

   2) qlcnic bug fixes from Himanshu Madhani and Manish Chopra.

   3) Update IPSEC MAINTAINERS entry, from Steffen Klassert.

   4) Administrative neigh entry changes should generate netlink
      notifications the same as event generated ones.  From Bob
      Gilligan.

   5) Netfilter SYNPROXY fixes from Patrick McHardy.

   6) Netfilter nft_reject endianness fixes from Eric Leblond"
