Re: [Madwifi-devel] Madwifi-free compile error

[Louay S. <lou...@li...>]

I am working on it and will post a solution soon, but I am sure it will
not be clean.

I look for long time on a way to do it cleanly, but my macro skills are
little, and it seems impossibles to me, I even look at many other
drivers in the kernel, and could not see any thing similar.

I guess we have no other option than the kloji  way!

About the interest, I bet you we will see more people interested when
they found ath5k is far from been ready,with too many missing features.
