   4 Subject: [PATCH] brcmfmac: allow 160MHz in custom regulatory rules
   5
   6 The driver has custom regulatory rules which had maximum bandwidth
   7 for 5GHz channels set to 80MHz. As a consequence the driver can
   8 not use 160MHz in AP mode even when the device supports it. So
   9 relax the rules allowing 160MHz. After wiphy_register() the channel
  10 flags are updated according what the device actually supports.
