From 39f6eb19cf85b08b8a926294750f5e79c50a6a7b Mon Sep 17 00:00:00 2001 From: Simon Vincent Date: Sun, 5 Oct 2014 20:23:12 +0200 Subject: [PATCH] ieee802154: 6lowpan: Drop PACKET_OTHERHOST skbs in 6lowpan 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.
