Subject: [PATCH net-next 7/8] sfc: make filter table probe caller responsible
 for adding VLANs

By making the caller of efx_mcdi_filter_table_probe() loop over the
 vlan_list calling efx_mcdi_filter_add_vlan(), instead of doing it in
 efx_mcdi_filter_table_probe(), the latter avoids looking in ef10-
 specific nic_data.
