Message-Id: <1259380301.2811.60.camel@achroite.uk.solarflarecom.com>
Date: Sat, 28 Nov 2009 03:51:41 +0000
From: Ben Hutchings <bhutchings@...arflare.com>
To: David Miller <davem@...emloft.net>
Cc: netdev@...r.kernel.org, linux-net-drivers@...arflare.com
Subject: [PATCH 27/32] sfc: Remove static PHY data and enumerations
New NICs have firmware managing the PHY, and we will discover the PHY
capabilities at run-time. Replace the static data with probe() and
test_name() operations.
