The firmware does accept the filter add/del commands and returns success. But, they are no-ops. To avoid confusion, remove the filter set handler so the app sees an error instead of silent failure. Also during the device configure time, enicpmd_vlan_offload_set would not print a warning message about unsupported VLAN filtering, because the caller specifies only ETH_VLAN_STRIP_MASK. This is wrong, as we should attempt to apply all requested offloads at the configure time. So, pass all VLAN offload masks, which triggers a warning message about VLAN filtering, if requested. Finally, enicpmd_vlan_offload_set should check both mask and rxmode.offloads, not just mask.
