   4 Subject: [PATCH] brcmfmac: update beacon IE after bss up and clear when AP
   5  stopped
   6
   7 Firmware doesn't update beacon/Probe Response vendor IEs correctly when
   8 bss is down, so we move brcmf_config_ap_mgmt_ie after BSS up. And host
   9 driver should clear IEs when AP stopped so that the IEs in host side will
  10 be synced with in firmware side.
