Subject: Re: [PATCH 1/2] net: ethernet: mtk_eth_soc: fix wrong use of new
 helper function

> In function mtk_foe_entry_set_vlan() the call to field accessor macro
> FIELD_GET(MTK_FOE_IB1_BIND_VLAN_LAYER, entry->ib1)
> has been wrongly replaced by
> mtk_prep_ib1_vlan_layer(eth, entry->ib1)
> 
> Use correct helper function mtk_get_ib1_vlan_layer instead.
