29 * the total BAR area is: number-of-vfs * per-vf-size. The number of VFs

36 * so as a baseline we can assume that we have the following BAR modes
41 * a) A segmented BAR that splits the mapped range into $PE_COUNT equally sized
43 * b) An un-segmented BAR that maps the whole address range to a specific PE.
46 * We prefer to use mode a) since it only requires one MBT entry per SR-IOV BAR
47 * For comparison b) requires one entry per-VF per-BAR, or:
