[PATCH 4/4] pch_gbe: Fix: Link configuration in module parameters was ignored

From: Ondrej Puzman
Date: Thu Nov 28 2013 - 04:46:18 EST


PHY configuration set in pch_gbe_phy_init_setting() by mii_ethtool_sset() was immedeiately reset by two calls of pch_gbe_phy_sw_reset().
Result of this bug was that module parameters like AutoNeg were ignored silently.
