Monitor mode isn't supported yet with brcmfmac, it's just an early work.
This also prepares brcmfmac to work stable with new firmwares which use
updated struct for passing STA info.

Subject: [PATCH] brcmfmac: detect firmware support for monitor interface

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.
