I'm adding WE support for a Texas Instruments driver for future chipsets.

Jean recommends reading the userspace tools > source code (which from my POV shows just /how/ broken WE is). [Eitan Bar] I see. Can you please point out if there's any driver currently supporting cfg80211 or nl80211 for reference? (which one are you using for testing?) > > johannes - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
