Synchronize the ath11k backports with the current ath-next tree. This replaces the management TLV pending fix with the upstreamed one, fixes traffic flooding when AP and monitor modes are used at the same time, fixes QCN9074 always showing -95 dBm for station RSSI in dumps, fixes potential crash on boot if spectral scan is enabled due to writing to unitialized memory and adds 11d scan offloading for WCN6750 and WCN6855.

Subject: [PATCH] ath11k: support setting FW memory mode via DT
|
|
|
|
ath11k is really memory intensive for devices with less that 1GB of RAM,
|
|
so lets allow saving a significant amount of memory by setting the FW to
|
|
Mode-1 via DTS for devices that need it.
|
|
|
|
However the drawback is reduced number of VDEV-s and peers which is a
|
|
reasonable tradeoff.
|
|
|
|
Mode-2 allows for further reduction, but it has further restrictions.
|
|
|
|
While we are here, lets add a print to be able to easily determine what
|
|
FW memory mode is being used.
