Subject: [PATCH] wifi: cfg80211: export DFS CAC time and usable state helper
|
|
functions
|
|
|
|
cfg80211 has cfg80211_chandef_dfs_usable() function to know whether
|
|
at least one channel in the chandef is in usable state or not. Also,
|
|
cfg80211_chandef_dfs_cac_time() function is there which tells the CAC
|
|
time required for the given chandef.
|
|
|
|
Make these two functions visible to drivers by exporting their symbol
|
|
to global list of kernel symbols.
|
|
|
|
Lower level drivers can make use of these two functions to be aware
|
|
if CAC is required on the given chandef and for how long. For example
|
|
drivers which maintains the CAC state internally can make use of these.
