Well, it seems I've got things to the shape when initialization and driver
attaching goes well and RTEMS seems to got it.
Unfortunatelly, when trying to open connection from host to guest while
using proper user-net command-line parameters, I see this debug output
comming from Qemu:

tcm509_receive: size=58
packet dhost=00:00:00:00:00:00, padr=21:03:76:12:09:75
padr_match result=0 (rx_filter=0x0007)

That's just snipped from more such lines, basically they just repeat.

>From looking into the source code, it seems dhost is destination host
ethernet address and I just wonder why is it set to zeros when it should
be 21:03:76:12:09:75. Do you think I should blame my changes or better
overlooking of some places where I should setup ethernet address in the
RTEMS driver, or is this just another issue with your 3c509 emulation?

Thanks,
Karel
