Pull networking fixes from David Miller:
 "Nothing earth shattering here, lots of small fixes (f.e. missing RCU
  protection, bad ref counting, missing memset(), etc.) all over the
  place:

   1) Use get_file_rcu() in task_file iterator, from Yonghong Song.

   2) There are two ways to set remote source MAC addresses in macvlan
      driver, but only one of which validates things properly. Fix this.
      From Alvin Šipraga.

   3) Missing of_node_put() in gianfar probing, from Sumera
      Priyadarsini.

   4) Preserve device wanted feature bits across multiple netlink
      ethtool requests, from Maxim Mikityanskiy.

   5) Fix rcu_sched stall in task and task_file bpf iterators, from
      Yonghong Song.

   6) Avoid reset after device destroy in ena driver, from Shay
      Agroskin.

   7) Missing memset() in netlink policy export reallocation path, from
      Johannes Berg.

   8) Fix info leak in __smc_diag_dump(), from Peilin Ye.

   9) Decapsulate ECN properly for ipv6 in ipv4 tunnels, from Mark
      Tomlinson.

  10) Fix number of data stream negotiation in SCTP, from David Laight.

  11) Fix double free in connection tracker action module, from Alaa
      Hleihel.

  12) Don't allow empty NHA_GROUP attributes, from Nikolay Aleksandrov"
