Hi!
Commenting out /sys/src/9/pc/etherigbe.c:1767 worked for me, at
least, for a while. It was kind of obvious, so maybe my mail was
kind of spam. But commenting it out is not all. #l is set up now,
but /net/ether0/addr gives me now sth. like ffffffff, so maybe
that's why i never get a connection to my dhcpd. I think that
has sth. to do with some function which sets up/reads the mac
address and isn't (correctly) implemented for my controller,
but I don't know much about nic drivers.

Best regards,
Philipp
