From bc07947332f064de1b8a2e383a8dc31cc4d8487c Mon Sep 17 00:00:00 2001 From: Wenzhuo Lu Date: Wed, 24 Jun 2015 11:25:51 +0800 Subject: [PATCH] ixgbe/base: update X550em LPLU This patch updates x550em LPLU (Low Power Link Up) to use the MAC ops setup_link function pointer. This removes redundant code and provides iXFI and KR support between internal and external PHY.
