Eric Dumazet b0de0cf4f5 tcp: autocork: take MSG_EOR hint into consideration 
tcp_should_autocork() is evaluating if it makes senses
to not immediately send current skb, hoping that
user space will add more payload on it by the
time TCP stack reacts to upcoming TX completions.

If current skb got MSG_EOR mark, then we know
that no further data will be added, it is therefore
futile to wait.

SOF_TIMESTAMPING_TX_ACK will become a bit more accurate,
if prior packets are still in qdisc/device queues.
