Synchronize the ath11k backports with the current ath-next tree. This backports several memory leak issues, PCI IRQ fixup, peer add locking fix as well as IPQ5018 support, though IPQ5018 support is unused for now. This allows to easily backport further fixes as cherry picking them has started requiring manual conflict resolution. Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] wifi: ath11k: Set ext passive scan flag to adjust passive
|
|
scan start time
|
|
|
|
Set the WMI_SCAN_FLAG_EXT_PASSIVE_SCAN_START_TIME_ENHANCE flag
|
|
while sending the scan command. If this flag is enabled when the
|
|
incoming scan request comes with a strict start time and its duration
|
|
overlaps with next TBTT, then target adjust the start time accordingly
|
|
for passive scan. Target supporting this feature will advertise
|
|
WMI_TLV_SERVICE_PASSIVE_SCAN_START_TIME_ENHANCE.
|
|
|
|
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01467-QCAHKSWPL_SILICONZ-1
