That would be a bad format to use, because it assumes Ethernet.
PXELINUX uses 01-xx-xx-xx-xx-xx-xx for Ethernet addresses, since 01 is
the ARP/DHCP media type for Ethernet.  The use of dashes rather than the
more commonly used colons is because colons are special in many
filesystems, and dashes is actually the official form as used by the
IEEE.  In a Unix environment it's easy enough to convert forms.
