From c74df29a8d119a09ccc5e50265e3383c76278f3d Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 16 May 2017 14:00:08 -0700 Subject: [PATCH] tcp: use tcp_jiffies32 to feed probe_timestamp Use tcp_jiffies32 instead of tcp_time_stamp, since tcp_time_stamp will soon be only used for TCP TS option.
