Subject: [PATCH] ixgbe: add GRO to vlan_features

When running a vlan -> bridge -> domU setup I was noticing poor RX
performance. It seems ixgbe and other drivers don't have NETIF_F_GRO set
in vlan_features and thus GRO is off by default for vlans.

I see no reason why the other drivers shouldn't be fixed. If this is OK
I will go off and fix the rest.
