From 0f8fdab1334cbd7e65b705cb5db6c3c1d757ffa0 Mon Sep 17 00:00:00 2001 From: Emil Tantilov Date: Sat, 31 Aug 2013 03:08:20 +0000 Subject: ixgbe: fix ethtool reporting of supported links for SFP modules This patch resolves an issue where the driver will display incorrect info for Q/SFP+ modules that were inserted after the driver has been loaded. This patch adds a call to identify_phy() in ixgbe_get_settings() prior to calling get_link_capabilities() which needs the PHY data in order to determine the correct settings.
