Unfortunately, you and he didn't communicate the key point.  What is 
wanted here is for
a REAL_TIME task to use the network card for a private protocol. 
 Real-time tasks
run in a completely different environment from Linux tasks, basically 
running in
x86 real mode, with no kernel services available.

Yes, standard net drivers will work for standard Linux networking under 
the control
of the operating system, but that is a totally different thing.
