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).

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>

AP: Do station poll in driver wrapper This offloads the station polling to driver wrappers, which may offload it again to the driver.
