The Max10 BMC on the Silicom n5010 PAC is slightly different than the
existing BMC's, so use a dedicated feature revision detect it.

Is there no way to query the mc for version info?
Do you mean reading the BMC variant (i.e. n5010 / d5005 / n3000) from a

Not in a uniform way across the different boards that I'm aware of. But
isn't this what the DFL feature revision is meant for?
