We do not recommend it,  but recommend to write Linux
specific drivers. Operating systems are quite different and you
get far better drivers if you really optimize them for specific OS.
That's especially important for performance critical drivers like
yours for high speed networking.

Also splitting drivers into generic and OS specific parts typically
leads to poor and overcomplicated design.

Anyways if you really want abstraction elsewhere then use the Linux
names for it. But it's really not recommended.
