In multi BSS setups it wasn't possible to set up an HT BSS in conjunction with a WEP/TKIP BSS. HT needed to be turned off entirely to allow WEP/TKIP BSSes to be used. In order to allow HT BSSes to coexist with non-HT WEP/TKIP BSSes add a new BSS conf attribute "disable_11n" which disables HT capabilities on a single BSS by suppressing HT IEs in the beacon and probe response frames. Furthermore, mark all STAs associated to a WEP/TKIP BSS as non-HT STAs. The disable_11n parameter is used internally; no new entry is parsed from hostapd.conf. This allows a non-HT WEP/TKIP BSS to coexist with a HT BSS without having to disable HT mode entirely. Nevertheless, all STAs associated to the WEP/TKIP BSS will only be served as if they were non-HT STAs. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com>
