This adds a QCA vendor specific nl80211 event to allow the driver to indicate a list of frequency ranges that should be avoided due to interference or possible known co-existance constraints. Such frequencies are marked as not allowed for P2P use to force groups to be formed on different channels. If a P2P GO is operating on a channel that the driver recommended not to use, a notification about this is sent on the control interface and upper layer code may decide to tear down the group and optionally restart it on another channel. As a TODO item, this could also be changed to use CSA to avoid removing the group. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
