| |
On MTK SoC ethernet, using NETIF_F_HW_VLAN_CTAG_RX in combination with hardware special tag parsing can pass the special tag port metadata as VLAN protocol ID. When the results is added as a skb hwaccel VLAN tag, it triggers a warning from vlan_do_receive before calling the DSA tag receive function. Remove this warning in order to properly pass the tag to the DSA receive function, which will parse and clear it.
