Subject: [net-next-2.6 12/12] ixgbe: convert to ethtool set_phys_id

From: Emil Tantilov <emil.s.tantilov@...el.com>

Based on the original patch submitted by Stephen Hemminger.

This patch makes the following changes:
- Change ETHTOOL_ID_INACTIVE return value to 2 (blinks/sec)
- Fix restoring of IXGBE_LEDCTL
