mac80211: adding 802.11n HT framework definitions
New structures: - ieee80211_ht_info: describing STA's HT capabilities - ieee80211_ht_bss_info: describing BSS's HT characteristics Changed structures: - ieee80211_hw_mode: now also holds PHY HT capabilities for each HW mode - ieee80211_conf: ht_conf holds current self HT configuration ht_bss_conf holds current BSS HT configuration - flag IEEE80211_CONF_SUPPORT_HT_MODE added to indicate if HT use is desired - sta_info: now also holds Peer's HT capabilities Signed-off-by: Ron Rindjunsky <ron.rindjunsky@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
