[ resend due to mail problems at my end ] Hi Jesse,
The backport of fac8e0f579695a3ecbc4d3cac369139d7f819971, "tunnels: Don't apply GRO to multiple layers of encapsulation", to linux-4.1.y seems to have missed a line. The 4.1 commit is 066b300e5be43cb61697539e2a3a9aac5afb422f. The potentially missing line is: - .gro_receive = ipv6_gro_receive, + .gro_receive = sit_gro_receive, I am not experiencing any bad symptoms. I simply noticed that the patch introduced a new function, sit_gro_receive, without introducing any users, and that same patch in linux-4.4.y does have a user. Regards, Joe
