This patch adds support for VLAN ctag based filtering at slave devices. The slave ethernet device may be capable of filtering ethernet packets based on VLAN ID. This requires that when the VLAN interface is created over an HSR/PRP interface, it passes the VID information to the associated slave ethernet devices so that it updates the hardware filters to filter ethernet frames based on VID. This patch adds the required functions to propagate the vid information to the slave devices.

The kill_vid / add_vid is not similar because during add_vid, if vlan_vid_add() succeeds for one port but fails for other, we need to delete it for the earlier port. We can only continue if vlan_vid_add() succeeds for both ports. That's the reason the switch case handling of add_vid can not match the same for kill_vid. Since cleanup of port is needed, it's not possible to synchronize add/kill code
We only care about HSR_PT_SLAVE_A and HSR_PT_SLAVE_B here. So it's okay to ignore HSR_PT_INTERLINK. It's a desired behaviour here.

If the desired behavior is to ignore INTERLINK port, I think you should explicitly skip them here, otherwise you will end-up in a nondeterministic state.
ret = vlan_vid_add(port->dev, proto, vid);switch (port->type) {case HSR_PT_SLAVE_A:if (ret) {netdev_err(dev, "add vid failed for Slave-A\n");return ret;}break;case HSR_PT_SLAVE_B:if (ret) {/* clean up Slave-A */netdev_err(dev, "add vid failed for Slave-B\n");vlan_vid_del(port->dev, proto, vid);
This code relies on a specific port_list order - which is actually respected at list creation time. Still such assumption looks fragile and may lead to long term bugs.
I think would be better to refactor the above loop handling arbitrary HSR_PT_SLAVE_A, HSR_PT_SLAVE_B order. Guestimate is that the complexity will not increase measurably.

Add support for VLAN addition/deletion in HSR mode. In HSR mode, even if the host port is not a member of the VLAN domain, the slave ports should simply forward the frames. So allow forwarding of all VLAN frames in HSR mode.
