Hi all,
I'd like to extend port capability using ML2 binding:profile. I checked
the official docs and it seems that there's no guide for it.
Is there any CLI support for port binding:profile?
Or is there any development guide on how to set up "profile"?

port_update out?
In my situation, I run a devstack environment and the bound segment is
None by default. Actually, I need this message to be sent out in any
situations.

Updated. I commented out the segment checking in _notify_port_updated of
ml2-plugin, and finally I can get port_update message on l2-agents.
Is there any side effect? It is working for me, but I'm not sure it is
the "real" solution.

Hi Gal, you reverted this patch [1] due to the broken pipeline. Could
you provide some debug information or detailed description? When I run
my devstack, I cannot reproduce the sync problem.

which bridge to use.
(2) Let Neutron decide interface name (tap-xxx) and bridge name
(brq-xxx), not Nova. As a result, when creating port, Neutron return
interface name and bridge name to Nova, so Nova has the right device
name to process. This helps Nova get rid of hard-code, but need lots
?
