   4 Subject: [PATCH] brcmfmac: detect firmware support for monitor interface
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit
   8
   9 Many/most of firmwares support creating monitor interface but only the
  10 most recent ones explicitly /announce/ it using a "monitor" entry in the
  11 list of capabilities.
  12
  13 Check for that entry and store internally info about monitor mode
  14 support using a new feature flag. Once we sort out all details of
  15 handling monitor interface it will be used when reporting available
  16 interfaces to the cfg80211.
  17
  18 Later some fallback detecion method may be added for older firmwares.
  19 For now just stick to the "monitor" capability which should be 100%
  20 reliable.
