Subject: [PATCH v2 1/2] 6lowpan: Only make 6lowpan links to IEEE802154 devices
Date: Sat, 5 Oct 2013 23:15:18 -0400 [thread overview]
Message-ID: <1381029319-6835-2-git-send-email-alan@signal11.us> (raw)
In-Reply-To: <1381029319-6835-1-git-send-email-alan-yzvJWuRpmD1zbRFIqnYvSA@public.gmane.org>
Refuse to create 6lowpan links if the actual hardware interface is
of any type other than ARPHRD_IEEE802154.
