[Intel-wired-lan] Does a VF know that it is "trusted"?

No, the intent is that the VF does not know its trusted or not.  It asks and if it *is* trusted, then the PF grants the request.  VF only knows if the request was granted or not.  That is the current design anyway.  Mitch can probably comment more.

Thanks,

Carolyn
