e1000e: don't check for alternate MAC addr on parts that don't support it
From: Bruce Allan <bruce.w.allan@intel.com>
The alternate MAC address feature is only supported by 80003ES2LAN and
82571 LOMs as well as a couple 82571 mezzanine cards. Checking for an
alternate MAC address on other parts can fail leading to the driver not
able to load. This patch limits the check for an alternate MAC address
to be done only for parts that support the feature.
This issue has been around since support for the feature was introduced
to the e1000e driver in 2.6.34.
