Subject: [PATCH] mac80211: add new acs_exclude_dfs option
The channel can be selected automatically at run time by setting
channel=acs_survey or channel=0, both of which will enable the ACS survey
based algorithm in hostapd. If the option acs_exclude_dfs is set in the
hostpad config DFS channels from ACS are excluded on channel selection.
This commit will add the possibilty to exclude the dfs channel on ACS
survey.
