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