You can set if_dname to anything you want it to be since we don't
actually do much with it (the cloning API being the major exception).
The only place it would be relevant is in if_mib where it's bogusly
exported with if_dunit smashed onto it in the IFDATA_DRIVERNAME case.
I've been meaning to add it to the ifconfig -v output for a while so
people who rename their interfaces can see it.

The one gotcha is that you'll presumably want the config file entries
and the module to be if_myri10ge which would mean that the ifconfig
autoloading hack wouldn't work.  That's not a problem for me since I
think it should die :), but this might be a minor, periodic support
