net: disallow drivers with buggy VLAN accel to register_netdevice()
Instead of jumping aroung bugs that are easily fixed just don't let them in: affected drivers should be either fixed or have NETIF_F_HW_VLAN_FILTER removed from advertised features. Quick grep in drivers/net shows two drivers that have NETIF_F_HW_VLAN_FILTER but not ndo_vlan_rx_add/kill_vid(), but those are false-positives (features are commented out). OTOH two drivers have ndo_vlan_rx_add/kill_vid() implemented but don't advertise NETIF_F_HW_VLAN_FILTER. Those are: +ethernet/cisco/enic/enic_main.c +ethernet/qlogic/qlcnic/qlcnic_main.c Signed-off-by: NMichał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
