[ath9k-devel] ath9k and kernel versions

[Jack Howarth <howarth@bromo.msbb.uc.edu>]

    Does anyone know if the current ath9k drivers will work
against either the tip linux kernel or the current 2.6.26-git12
stable linux kernel? I have been able to generate an ath9k
patch against the tip kernel git which applies cleanly to both
and builds the ath9k driver. I've only tested the ath9k driver
under the tip kernel so far using...

alias ath0 ath9k
alias wifi0 ath9k

in /etc/modprobe.conf which gives the following ath9k kernel messages
in dmesg...

However the NetworkManager seems unable to get an address
from the AP. Since I have been using the madwifi drivers before
these kernels (built using the rawhide development srpm as
a framework), I have to remove...

options ath9k autocreate=sta

from modprobe.conf. I am wondering if my problems with the
AP not getting an ip address could be due to the absence of
some option for the ath9k driver which would set it in sta mode?
Also I am unclear if the ath5k/ath9k drivers would require more
careful configuration in the NetworkManager (since they don't have
the 'autocreate=sta' line in modprobe.conf)? Or is it likely that
I am missing some critical wireless patch in tip and/or the stable
kernel. I was hoping to be able to test this driver under at least
the linus-kernel git or the current stable git so that I can keep
using the rawhide srpm and associated patches for Fedora 9. Thanks
in advance for any advice as I am baffled as to why the driver
isn't working.

ps I am connecting to a WRT-150N configured for G wireless connections
only.
