I don't see much point in having more than 255 sub-namespaces per OUI,
do you?

Where are you taking 8 fields from? After the vendor extensions bit, the
vendor extension puts vendor-defined presence bits into the it_present
bitmap. Therefore, you have an unlimited number of fields per vendor
sub-namespace, as such I see little reason to support more than 255
sub-namespaces.
