Subject: [net-next-2.6 01/12] e1000e: implement ethtool set_phys_id
From: Bruce Allan <bruce.w.allan@...el.com>
Based on a patch from Stephen Hemminger <shemminger@...tta.com>.
The new ethtool set_phys_id takes over controlling the LED for
identifying boards. This fixes the lockout during that period.
For this device lots of extra infrastructure can also be removed by
using set_phys_id.
v2: - return blink frequency for parts that do not support blink in h/w
- add blink_led function pointers for devices that do support blink
in h/w to cleanup the test for this functionality
