Add preliminary IEEE 802.11n support into hostapd This commit brings in cleaned up version of IEEE 802.11n implementation from Intel (1). The Intel tarball includes number of other changes, too, and only the changes specific to IEEE 802.11n are brought in here. In addition, this does not include all the changes (e.g., some of the configuration parameters are still missing and driver wrapper changes for mac80211 were not included).

Do not process Action frames twice in hostapd SME/MLME Commit 88b32a99d30894b2d6bb391371c442fc117edbab added support for using some Action frame processing in hostapd for drivers that handle most of SME/MLME internally (it added FT, this has since be extended for SA Query and WNM). However, this was added in a way that ended up getting both the hostapd_rx_action() and hostapd_action_rx() called for Action frames. This could result in an attempt to process FT, SA Query, and WNM Action frames twice. There is need for more significant cleanup in Action frame processing in hostapd depending on the driver type, but as a simple step to avoid issues, skip the hostapd_action_rx() call if hostapd_rx_action() processed the frame.

hostapd: Allow coexistance of HT BSSes with WEP/TKIP BSSes 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>
