The whole purpose of IFF_NEEDSGIANT is because usb1 *needs* it.
I'm currenly using my own custom if_ndis/ndis code with usb stuff
removed and it works fine without that flag.
Anyway, usb2 is going to replace usb1 very soon and in that case
if_ndis & ndis will stop working.
So comment out whole ndisulator from build until it get ported to usb2.
