Message-ID: <1377175832.1703.18.camel@bwh-desktop.uk.level5networks.com>
Date: Thu, 22 Aug 2013 13:50:32 +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 net-next 13/32] sfc: Move siena_reset_hw() and
siena_map_reset_reason() into MCDI module
These implementations should work for EF10 too. Rename them
accordingly.
