From f859b4af1c52493ec21173ccc73d0b60029b5b88 Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Thu, 30 Nov 2017 10:41:14 +0800 Subject: sit: update frag_off info After parsing the sit netlink change info, we forget to update frag_off in ipip6_tunnel_update(). Fix it by assigning frag_off with new value. Reported-by: Jianlin Shi Signed-off-by: Hangbin Liu Acked-by: Nicolas Dichtel Signed-off-by: David S.
