It wasn't particularly WiMax, but when I worked on HSPA+ device,
usie(4) it worked like that, set up usb xfers and throw ethernet
packets at the device, that was it. Probably, one simple generic stack
would work for most of them if needed.
The problem I had was there is no mechanism to pass device info (i.e
link state up/down, signal strength, IP addresses) to other part of
the system. I thought about adding it, but I haven't because there
isn't lots of demand.
