If anyone has any objections, please let me know. ------------------ From: Hangbin Liu [ Upstream commit f859b4af1c52493ec21173ccc73d0b60029b5b88 ] 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.
