   4 Subject: [PATCH 04/18] mesh: use setup completion callback to complete mesh
   5  join
   6
   7 mesh join function is the last function to be called during
   8 mesh join process, but it's been called a bit earlier than
   9 it's supposed to be, so that some mesh parameter values
  10 such as VHT capabilities not applied correct when mesh join
  11 is in process. Moreover current design of mesh join that is called
  12 directly after mesh initialization is not suitable for DFS channels
  13 to use, since mesh join process should be paused until DFS CAC is
  14 done and resumed once it's done.
  15 Using setup completion callback is how AP mode is using for DFS channels
  16 and mesh can use the same way.
  17 The callback will be called by hostapd_setup_interface_complete_sync.
