I'd suggest to have a look to app/basemon. It contains
all required routines for accessing the RTL8019AS without
using more complicated Nut/OS functions. Try to read the
chip ID first. If that works, it shouldn't be too difficult
to modify the Nut/OS driver for your specific hardware.

But keep in mind: Ethernet may transmit up to 1500 bytes
in one packet. The ATmega internal RAM will soon reach its
limits.
