From 9c21d2fc41c0c8930600c9dd83eadac2e336fcfa Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 17 May 2018 14:47:29 -0700 Subject: tcp: add tcp_comp_sack_nr sysctl This per netns sysctl allows for TCP SACK compression fine-tuning. This limits number of SACK that can be compressed. Using 0 disables SACK compression. Signed-off-by: Eric Dumazet Acked-by: Neal Cardwell Signed-off-by: David S.
