Cover letter [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.

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
