Feels like we can adopt the same mechanics. Although, unless i am
misreading, it seems Ido's patches cover a slightly different use
case: not totally synchronous in successfully pushing the rule to
hardware i.e could be sitting somewhere in firmware on its way to
the ASIC (and at least your connectx driver seems to only be
relinquishing control after confirming the update succeeded).
Am i mistaken Ido?
