From d2329f102d846214e449941289c7009e16be01a0 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 25 Apr 2017 10:15:38 -0700 Subject: tcp: do not pass timestamp to tcp_rack_advance() No longer needed, since tp->tcp_mstamp holds the information. This is needed to remove sack_state.ack_time in a following patch. Signed-off-by: Eric Dumazet Acked-by: Soheil Hassas Yeganeh Acked-by: Neal Cardwell Signed-off-by: David S.
