Subject: [PATCH v2 next-next 03/12] gre6: Fix flag translations
Date: Fri, 6 May 2016 13:04:47 -0700 [thread overview]
Message-ID: <1462565096-4076043-4-git-send-email-tom@herbertland.com> (raw)
In-Reply-To: <1462565096-4076043-1-git-send-email-tom@herbertland.com>
GRE for IPv6 does not properly translate for GRE flags to tunnel
flags and vice versa. This patch fixes that.
