====================
tcp: defer shinfo->gso_size|type settings

We put shinfo->gso_segs in TCP_SKB_CB(skb) a while back for performance
reasons.

This was in commit cd7d8498c9 ("tcp: change tcp_skb_pcount() location")

This patch series complete the job for gso_size and gso_type, so that
we do not bring 2 extra cache lines in tcp write xmit fast path,
and making tcp_init_tso_segs() simpler and faster.
