You could sort that out with udev rules on each machine.
Look in the directory /etc/udev/rules.d for the file
you'll need a script which looks for the HWaddr (MAC) address matching
the 10gig cards
and edit the SUBSYSTEM line for that interface.
As you say it should not matter - but I would get them all consistent anyway.
