Yes, this also matches the recollection of the joint conversation in
Denver. Please look at the "Ironic x-project discussion - Smartnics"
section in

> Greetings everyone,
> Now that the PTG is over, I would like to go ahead and get the
> specification that was proposed to ironic-specs updated to represent
> the discussions that took place at the PTG.
> A few highlights from my recollection:
> * Ironic being the source of truth for the hardware configuration for
> the neutron agent to determine where to push configuration to. This
> would include the address and credential information (certificates
> right?).
> * The information required is somehow sent to neutron (possibly as
> part of the binding profile, which we could send at each time port
> actions are requested by Ironic.)
> * The Neutron agent running on the control plane connects outbound to
> the smartnic, using information supplied to perform the appropriate
> network configuration.
> * In Ironic, this would likely be a new network_interface driver
> module, with some additional methods that help facilitate the
> work-flow logic changes needed in each deploy_interface driver module.
> * Ironic would then be informed or gain awareness that the
> configuration has been completed and that the deployment can proceed.
> (A different spec has been proposed regarding this.)
> I have submitted a forum session based upon this and the agreed upon
> goal at the PTG was to have the ironic spec written up to describe the
> required changes.
> I guess the next question is, who wants to update the specification?
