From 61ccbb684421d374fdcd7cf5d6b024b06f03ce4e Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Thu, 13 Mar 2014 12:41:57 +0100 Subject: [PATCH] ether: add loopback type ETH_P_LOOPBACK Per IEEE 802.3*, the correct packet type for loopback 0x9000. There's already one ETH_P_LOOP 0x0060, which has been there for ages, however it's plainly wrong as anything that small is considered a length field. We can't remove it because legacy, so add a new type which corresponds to the correct id. http://www.iana.org/assignments/ieee-802-numbers/ieee-802-numbers.xhtml CC: "David S.
