Subject: [PATCH net-next 0/3] tcp: tso defer improvements

This series makes tcp_tso_should_defer() a bit smarter :

1) MSG_EOR gives a hint to TCP to not defer some skbs

2) Second patch takes into account that head tstamp
   can be in the future.

3) Third patch uses existing high resolution state variables
   to have a more precise heuristic.

Eric Dumazet (3):
  tcp: do not try to defer skbs with eor mark (MSG_EOR)
  tcp: refine tcp_tso_should_defer() after EDT adoption
  tcp: get rid of tcp_tso_should_defer() dependency on HZ/jiffies
