[PATCH v3 01/15] mesh: factor out mesh join function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Peter Oh <peter.oh@xxxxxxxxxxxxxxxxx>

mesh join function consitss of 2 parts which are preparing
configurations and sending join event to driver.
Since physical mesh join event could happen either right
after mesh configuration is done or after CAC is done
in case of DFS channel is used, factor out the function
into 2 parts to reduce redundant calls.
