   4 Subject: [PATCH 08/19] 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.
  12 Moreover current design of mesh join that is called directly
  13 after mesh initialization isn't suitable for DFS channels to use,
  14 since mesh join process should be paused until DFS CAC is
  15 done and resumed after it's done.
  16 The callback will be called by hostapd_setup_interface_complete_sync.
  17 There is possiblity that completing mesh init fails, so add error
  18 handle codes.
