ipv6: Don't send packet to big messages to self
Calling icmpv6_send() on a local message size error leads to an incorrect update of the path mtu in the case when IPsec is used. So use ipv6_local_error() instead to notify the socket about the error. Reported-by: Jiri Bohac <jbohac@suse.cz> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David S.
