From 33e34e735fd4227b49735f1fc059dc9646abd1c6 Mon Sep 17 00:00:00 2001 From: David Lebrun Date: Sun, 10 Sep 2017 14:22:01 +0100 Subject: ipv6: sr: remove duplicate routing header type check As seg6_validate_srh() already checks that the Routing Header type is correct, it is not necessary to do it again in get_srh(). Fixes: 5829d70b ("ipv6: sr: fix get_srh() to comply with IPv6 standard "RFC 8200") Signed-off-by: David Lebrun Signed-off-by: David S.
