Pull networking changes from David Miller:
 "Most importantly this should cure the ipv4-mapped ipv6 socket TCP
  crashes some people were seeing, otherwise:

   1) Fix e1000e autonegotiation handling regression, from Tushar Dave.

   2) Fix TX data corruption race on e1000e down, also from Tushar Dave.

   3) Fix bfin_sir IRDA driver build, from Sonic Zhang.

   4) AF_PACKET mmap() tests a flag in the TX ring shared between
      userspace and the kernel for an internal consistency check.  It
      really shouldn't do this to validate the kernel's own behavior
      because the user can corrupt it to be any value at all.  From
      Daniel Borkmann.

   5) Fix TCP metrics leak on netns dismantle, from Eric Dumazet.

   6) Orphan the anonymous TCP socket from the SKB in
      ip_send_unicast_reply() so that the rest of the stack needn't see
      it.  Otherwise we get selinux problems of all sorts, from Eric
      Dumazet.

      This is the best way to fix this since the socket is just a place
      holder for sending packets in a context where we have no real
      socket at all.

   7) Fix TUN detach crashes, from Stanislav Kinsbursky.

   8) dev_set_alias() leaks memory on krealloc() failure, from Alexey
      Khoroshilov.

   9) FIB trie must use call_rcu() not call_rcu_bh(), because this code
      is not universally invoked from software interrupts.  From Eric
      Dumazet.

  10) PPTP looks up ipv4 routes with the wrong network namespace, fix
      from Gao Feng."
