nl80211/cfg80211: Add support to disable CCK rate for management frame
Add a new nl80211 attribute to specify whether to send the management frames in CCK rate or not. As of now the wpa_supplicant is disabling CCK rate at P2P init itself. So this patch helps to send P2P probe request/probe response/action frames being sent at non CCK rate in 2GHz without disabling 11b rates. This attribute is used with NL80211_CMD_TRIGGER_SCAN and NL80211_CMD_FRAME commands to disable CCK rate for management frame transmission.
