Subject: [PATCH] gre6: allow to update all parameters via rtnl
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: 3d8fd70921d8 ("gre: Support GRE over IPv6")
