It isn't clear to me why a separate driver from the existing ral(7D) is needed because this is attached via USB rather that PCI. Is the RT2500USB that different to the RT2500 that the ral(7D) driver supports that a new driver is needed ? However I did a tiny bit of research and found that *BSD have a similar ral/ural split so it seems that other operating systems chose this split.

For Solaris devices, the DDI for USB is *vastly* different than the PCI DDI at some core fundamental concepts. It would be much harder to have a unified RAL driver, than (for example) a unified pcwl (PCI/PCMCIA). It may be possible to have a common library of shared functionality, but that may be more work than it is worth. Put another way, I think Quaker/Cecilia's plan here makes perfect sense. > > Also is this case setting any precedent that we should attempt to > prefix USB NIC drivers with 'u' ? I don't read it that way. It may make sense to use a 'u' prefix sometimes (as in this case), but I think we should still do it on a case by case basis. Anyway, this is a fasttrack (or maybe even self-review?), so I'm not sure we can even use it to set precedent like that.

No. Becuase the driver is ported from BSD, we'd like to use the same driver name with BSD, like other drivers, such as wpi, rtw.
