Subject: [PATCH bluetooth-next 2/2] ieee802154: 6lowpan: Drop PACKET_OTHERHOST skbs in 6lowpan
Date: Sun, 5 Oct 2014 20:23:12 +0200 [thread overview]
Message-ID: <1412533392-4072-3-git-send-email-alex.aring@gmail.com> (raw)
In-Reply-To: <1412533392-4072-1-git-send-email-alex.aring@gmail.com>
From: Simon Vincent <simon.vincent@xsilon.com>
There is no point processing pkts which are PACKET_OTHERHOST
in 6lowpan as they are discarded as soon as they reach the
ipv6 layer. Therefore we should drop them in the 6lowpan layer.
