Synchronize the ath11k backports with the current ath-next tree.
This introduces support for MBSSID and EMA, adds factory test mode and
some new HTT stats.

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.
