Ah, finally. I was actually waiting someone would spot this ...

Hmm. Seeing that we're getting more and more of these type of drivers
(cf bnx2 / bnx2i / cnic, enic / fnic, and at least one other in the pipe)
one does wonder whether we should establish a separate directory for
these kind of things.
drivers/virtual or drivers/shared springs to mind.

Having them in the network directory is probably not the
correct choice.

Cheers,

Hannes
