[PATCH net-next 02/15] tcp: introduce tcp_jiffies32

2017-05-16 Thread Eric Dumazet
We abuse tcp_time_stamp for two different cases : 1) base to generate TCP Timestamp options (RFC 7323) 2) A 32bit version of jiffies since some TCP fields are 32bit wide to save memory. Since we want in the future to have 1ms TCP TS clock, regardless of HZ value, we want to cleanup things.
