Vladimir Oltean 6666cebc5e net: dsa: sja1105: Add support for VLAN operations ... VLAN filtering cannot be properly disabled in SJA1105. So in order to emulate the "no VLAN awareness" behavior (not dropping traffic that is tagged with a VID that isn't configured on the port), we need to hack another switch feature: programmable TPID (which is 0x8100 for 802.1Q). We are reprogramming the TPID to a bogus value which leaves the switch thinking that all traffic is untagged, and therefore accepts it. Under a vlan_filtering bridge, the proper TPID of ETH_P_8021Q is installed again, and the switch starts identifying 802.1Q-tagged traffic.
