Up until now we only allowed VLAN devices to be put in a VLAN-unaware
bridge, but some users need the ability to enslave physical ports as
well.

This is achieved by mapping the port and VID 1 to the bridge's vFID,
instead of the port and the VID used by the VLAN device.

The above is valid because as long as the port is not enslaved to a
bridge, VID 1 is guaranteed to be configured as PVID and egress
untagged.

Maybe I am missing something in the setup, but I am not getting
host-to-host connectivity. I booted a switch with this patch, configured
a bridge:

I'm waiting for this discussion to be fully resolved before applying this
patch.  Just FYI...

Ido:

IPv4 works at boot; IPv6 requires the mcast snooping disable. For this
vlan-unaware bridges can that be set automatically?

And then, what are the options for lldp?
