Hello guys,
I had using Luis's ACS patch for a long time, I patched this patch on the
hostapd 1.0 source code, and made some fixes for it too.
The fix below change a bug when we check the secondary_channel, and avoid
accessing the NULL pointer.
I also attach the all in one patch based on hostapd 1.0 in this mail, you can
take a try.
