net/vmxnet3: add VLAN filter capability
net/vmxnet3: add VLAN filter capability

The driver supports VLAN filtering, but the option is not included in
the advertised list of capabilities. Thus any attempt to enable VLAN
filtering always fails. Update the list of offload capabilities to
include DEV_RX_OFFLOAD_VLAN_FILTER.
