I cloned the PCnet driver into a vmWare compatible. The network tests work
there, except for the message, which is in fact the same on the NS driver.
The problem arises when triing to debug accross the same network interface. I
guess that somekind of IP and MAC multicast must be enabled so that RedBoot
and the application networking can use the same interface.
If the multicast feature is needed for GDB, I'll try to implement it in the
vmWare driver first (after the hollydays if not this weekend).
Thanks
