[Click] Feedback from madwifi in Click

[Peter De Cleyn]

Hi David,

Thanks for trying! I'll try to see where this support was dropped and will
address it to the madwifi mailinglist too. I already contacted John Bicket,
the original author of the madwifi-stripped driver and who ported the
functionality in to the regular driver.

I'll keep you posted

Peter
