Traffic from other +ports receives a skb_metadata_dst() with the correct port and is demuxed +properly. + +Looking at mtk_poll_rx(), it becomes apparent that this driver uses the +skb vlan hwaccel area: + + union { + u32 vlan_all; + struct { + __be16 vlan_proto; + __u16 vlan_tci; + }; + }; + +as a temporary storage for the VLAN hwaccel tag, or the DSA hwaccel tag. +If this is a DSA master it's a DSA hwaccel tag, and finally clears up +the skb VLAN hwaccel header. + +I'm guessing that the problem is the (mis)use of API. +skb_vlan_tag_present() looks like this: + + #define skb_vlan_tag_present(__skb) (!!(__skb)->vlan_all) + +So if both vlan_proto and vlan_tci are zeroes, skb_vlan_tag_present() +returns precisely false.
