From 5bb18eb6e464694ca851bd9b86d64ab747ecbcbd Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Thu, 3 Dec 2015 17:21:50 +0100 Subject: [PATCH] gre6: allow to update all parameters via rtnl [ Upstream commit 6a61d4dbf4f54b5683e0f1e58d873cecca7cb977 ] Parameters were updated only if the kernel was unable to find the tunnel with the new parameters, ie only if core pamareters were updated (keys, addr, link, type). Now it's possible to update ttl, hoplimit, flowinfo and flags. Fixes: c12b395a4664 ("gre: Support GRE over IPv6") Signed-off-by: Nicolas Dichtel Signed-off-by: David S.
