[ Upstream commit 6750c87074c5b534d82fdaabb1deb45b8f1f57de ]
qlge_fix_features() is not supposed to modify hardware or driver state, rather it is supposed to only fix requested fetures bits. Currently qlge_fix_features() also goes for interface down and up unnecessarily if there is not even any change in features set.
This patch changes/fixes following -
1) Move reload of interface or device re-config from qlge_fix_features() to qlge_set_features(). 2) Reload of interface in qlge_set_features() only if relevant feature bit (NETIF_F_HW_VLAN_CTAG_RX) is changed. 3) Get rid of qlge_fix_features() since driver is not really required to fix any features bit.
