In a word, I would say: no.

When developing a non-GPL kernel driver, one finds themselves on very 
shaky legal ground. Unless one is 100% sure their code is not legally 
considered a derived work from the kernel, it's likely a GPL violation.

One could point out the pile of other Ethernet drivers in the kernel 
from the likes of Intel, Broadcom, etc. and ask why those companies did 
not feel the need to "protect their IP" in this manner.. as well as the 
significant advantages of having their driver in the mainline kernel, 
and the horrible disadvantages of trying to manage closed-source drivers..
