    qed: Introduce VFs · 1408cc1f
    Yuval Mintz authored
    This adds the qed VFs for the first time -
    The vfs are limited functions, with a very different PCI bar structure
    [when compared with PFs] to better impose the related security demands
    associated with them.
    
    This patch includes the logic neccesary to allow VFs to successfully probe
    [without actually adding the ability to enable iov].
    This includes diverging all the flows that would occur as part of the pci
    probe of the driver, preventing VF from accessing registers/memories it
    can't and instead utilize the VF->PF channel to query the PF for needed
    information.
