Heya, my laptop has an intel ipw2200 wireless adapter, which runs nice.
But I am unable to bring up the rtap interface which will deliver me all the packages unfiltered from the firmware
# echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
# ifconfig rtap0 up
SIOCSIFFLAGS: Invalid argument
I read on a mailinglist for the OLPC someone with a similar problem fixed it that way:
Thanks; I have that working now. We weren't setting the MAC address on
the rtap interface, so the kernel was refusing to bring the interface up
because its address was invalid. That check for a valid MAC address
doesn't happen in the older kernel that we're using on the XOs.

But trying to set a real macaddress doesn't work :-/
# ifconfig rtap0
rtap0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-B9-99-00-00-00-00-00-00-00-00

# ifconfig rtap0 hw ether 00:0F:25:BD:A6:12
SIOCSIFHWADDR: Invalid argument
Does anybody have an idea what could be going wrong? I am using the 2.6.24 kernel from [testing], it worked on arch some months ago with my other laptop (that one is broke now)
[EDIT] Ok, I rechecked using kernel 2.6.23, and this one is working fine :-/
Guess that is more for the bugtracker
