Pull two networking fixes from David S. Miller:

1) Thanks to Willy Tarreau and Eric Dumazet, we've unlocked a bug that's
   been present in do_tcp_sendpages() since that function was written in
   2002.

   When we block to wait for memory we have to unconditionally try and
   push out pending TCP data, otherwise we can block for an unreasonably
   long amount of time.

2) Fix deadlock in e1000, fixes kernel bugzilla 43132

   From Tushar Dave.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  e1000: Prevent reset task killing itself.
  tcp: do_tcp_sendpages() must try to push data out on oom conditions
