Subject: [PATCH] brcmfmac: detect firmware support for monitor interface
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
|
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.
