From: Corcodel Marian <hidden>
Date: 2015-08-01 17:20:35
Add parameter ff_dup wich disable advertise 10/100Mbs duplex full for card wich start on low speed on full duplex.Verry strange with this patch First insert module with ff_dup=1 link is good , unload module, load module wo parameter ff_dup and is full duplex and full speed on RTL_GIGA_MAC_VER_09.
