Eric Woudstra 96450df197 bridge: No DEV_PATH_BR_VLAN_UNTAG_HW for dsa foreign
In network setup as below:

             fastpath bypass
 .----------------------------------------.
/                                          \
|                        IP - forwarding    |
|                       /                \  v
|                      /                  wan ...
|                     /
|                     |
|                     |
|                   brlan.1
|                     |
|    +-------------------------------+
|    |           vlan 1              |
|    |                               |
|    |     brlan (vlan-filtering)    |
|    |               +---------------+
|    |               |  DSA-SWITCH   |
|    |    vlan 1     |               |
|    |      to       |               |
|    |   untagged    1     vlan 1    |
|    +---------------+---------------+
.         /                   \
 ----->wlan1                 lan0
       .                       .
       .                       ^
       ^                     vlan 1 tagged packets
     untagged packets

br_vlan_fill_forward_path_mode() sets DEV_PATH_BR_VLAN_UNTAG_HW when
filling in from brlan.1 towards wlan1. But it should be set to
DEV_PATH_BR_VLAN_UNTAG in this case. Using BR_VLFLAG_ADDED_BY_SWITCHDEV
is not correct. The dsa switchdev adds it as a foreign port.

The same problem for all foreignly added dsa vlans on the bridge.

First add the vlan, trying only native devices.
If this fails, we know this may be a vlan from a foreign device.

Use BR_VLFLAG_TAGGING_BY_SWITCHDEV to make sure DEV_PATH_BR_VLAN_UNTAG_HW
is set only when there if no foreign device involved.
