> Getting the pf_id from the function number was a good place to start, but
> when the PF was setup in pass-thru mode, the PCI bus/device/function was
> virtualized and the number in the VM is different from the number in the
> bare metal. This caused HW configuration issues when the wrong pf_id was
> used to set up the HMC and other structures. The PF_FUNC_RID register has
> the real bus/device/function information as configured by the BIOS, so use
> that for a better number.
