Sorry to bristle, here, please don't take it personally. This is
very frustrating to me...
Considering that I'm talking SBUS and not PCI at the moment, I think
that's a straw man, and I find it difficult to believe that, just because
"there is no MI way of (retrieving the value)" from PCI, we are unwilling
to make it available at an MD level where it would be appropriate.
In fact, it could be MADE MI by having a MD hook for it -- if the hook
isn't there (because it doesn't apply at that point), we punt. If the
hook IS there, then it shouldn't really be that big a deal. This is
all from the point of view that, conceptually, it should work, as seen
through the eyes of an exhausted, confused individual...
[i.e. no, I can't code this, but I sense it's possible, somehow.]
in the meantime, if someone can find me the OBP commands by which I can
even temporarily add a local-mac-address property to my hme, I'd greatly
