Subject: [PATCH 30/50] wifi: brcmfmac: check connection state before querying
|
|
station info
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
|
In station mode, brcmf_cfg80211_get_station() queries the firmware for
|
|
station info even when not connected to an AP. This results in error
|
|
-52 (EBADE) from firmware and noisy log messages:
|
|
|
|
brcmf_cfg80211_get_station: GET STA INFO failed, -52
|
|
|
|
Add a check for BRCMF_VIF_STATUS_CONNECTED before querying station
|
|
info in station mode. AP mode is not affected as it needs to query
|
|
info about connected clients regardless of its own connection state.
