After your persistent naming patches, I thought we have GUID based naming scheme which doesn't care about its underlying bus. So mdevs will be able to use current GUID based naming scheme we already have. Additionally, if user prefers, mdev alias, we can extend systemd/udev to use mdev alias based names (like PCI bdf). Such as, rocem<alias1> ibm<alias2> Format is: <link_layer><m><alias> m -> stands for mdev device (similar to 'p' for PCI)
