Regression in 3.7-rc2 for b43 and b43legacy

[Larry Finger <Larry.Finger@lwfinger.net>]

Johannes,

I have discovered that both b43 and b43legacy broke somewhere between 3.7-rc1 
and 3.7-rc2. The problem was bisected to commit fe57d9f. The commit message is

     mac80211: track whether to use channel contexts

     Depending on the driver, channel contexts may be used or
     not. If they are used, the driver must have support for
     hardware scan and remain-on-channel; otherwise the driver
     must not advertise support for multiple channels.

     Also prohibit WDS type interfaces when channel contexts
     are to be used as there's no clear definition of which
     channel they use.

It seems likely that the drivers are inadvertently advertising support for 
multiple channels, What must be done to turn off this "feature"?

Thanks,

Larry
