From b468645d72c2b4a15512f0a18e77670ea058b861 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Mon, 15 Nov 2010 11:23:06 +0100 Subject: [PATCH] netfilter: xt_LOG: do print MAC header on FORWARD I am observing consistent behavior even with bridges, so let's unlock this. xt_mac is already usable in FORWARD, too. Section 9 of http://ebtables.sourceforge.net/br_fw_ia/br_fw_ia.html#section9 says the MAC source address is changed, but my observation does not match that claim -- the MAC header is retained.
