Subject: e1000: FIX: firmware handover bits
From: Bruce Allan <bruce.w.allan@xxxxxxxxx>
Upon code inspection it was spotted that the firmware handover bit get/set
mismatched, which may have resulted in management issues on PCI-E adapters.
Setting them correctly may fix some management issues such as arp routing etc.
