net: ethernet: ti: cpsw: allow untagged traffic on host port
Now untagged vlan traffic is not support on Host P0 port. This patch adds in ALE context bitmap of VLANs for which Host P0 port bit set in Force Untagged Packet Egress bitmask in VLANs ALE entries, and adds corresponding check in VLAN incapsulation header parsing function cpsw_rx_vlan_encap().
