I think it's the other way around, with the flag it enters promiscuos
mode. But I will double check the documentation.

Btw, I just tested on our ethernut1 based board with atmega128, and
the httpd example is running perfectly fine here. It's not a busy
network, and I haven't tried to flood it, but it's much more than what
I see in the AVR32 EVK1105 and from what Ulrich described, SAM7X.
