Date: Thu, 22 Aug 2013 20:26:29 +0100
From: Ben Hutchings <bhutchings@...arflare.com>
To: David Miller <davem@...emloft.net>
CC: <netdev@...r.kernel.org>, <linux-net-drivers@...arflare.com>
Subject: [PATCH RESEND net-next 05/16] sfc: Move more Falcon-specific code
and definitions into falcon.c
In particular, fold in the whole of falcon_xmac.c.
Drop some entirely unused definitions.
