[En-Nut-Discussion] Crystal CS8900A Device Drivers for ethernut

[Jon Anders Haugum]

I've been able to provoke it quite easily by flood-pinging a CS8900.

Also I once made a hybrid with it. Meaning I still used the interrupt, but
at timed intervals I polled the device in addition. Worked excellent, but
this wasn't with the nut.
