From: Dmitry Lebed <dlebed@xxxxxxxxxxxxx> Hi all, Here is a patch set with nl80211 FREQ_ATTR_NO_* usage added. Currently linux kernel is verifying that channel settings are allowed in terms of supported channel BW attributes. Sometimes HW or driver may limit some channel configurations, but hostapd is not taking it into account and it leads to unsupported channel can be selected manually, by ACS and by DFS, leading to hostapd shutdown e.g. in case of wrong channel is being selected in a response to radar event. This patch set do not introduce support of any new channel modes, it just adds new checks to make hostapd avaliable channel set view consistent with linux kernel view.
