From 756ee1729b2feb3a45767da29e338f70f2086ba3 Mon Sep 17 00:00:00 2001 From: Lawrence Brakmo Date: Wed, 11 May 2016 10:02:13 -0700 Subject: tcp: replace cnt & rtt with struct in pkts_acked() Replace 2 arguments (cnt and rtt) in the congestion control modules' pkts_acked() function with a struct. This will allow adding more information without having to modify existing congestion control modules (tcp_nv in particular needs bytes in flight when packet was sent). As proposed by Neal Cardwell in his comments to the tcp_nv patch. Signed-off-by: Lawrence Brakmo Acked-by: Yuchung Cheng Signed-off-by: David S.
