Willem de Bruijn f066e2b091 net-timestamp: cumulative tcp timestamping fixes ...

A set of small fixes pointed out just after the merge:
- make tcp_tx_timestamp static
- make tcp_gso_tstamp static
- use before() to compare TCP seqno, instead of cast to u64
- add tstamp to tx_flags in GSO, instead of overwrite tx_flags
- record skb_shinfo(skb)->tskey for all timestamps, also HW.
- optimization in tcp_tx_timestamp:
  call sock_tx_timestamp only if a tstamp option is set.
