Subject: [PATCH] ath10k: Fix sending NULL/ Qos NULL data frames for
|
||
|
|
QCA99X0 and later
|
||
|
|
|
||
|
|
For chipsets like QCA99X0, IPQ4019 and later we are not getting proper
|
||
|
|
NULL func status (always acked/successs !!) when hostapd does a
|
||
|
|
PROBE_CLIENT via nullfunc frames when the station is powered off
|
||
|
|
abruptly (inactive timer probes client via null func after the inactive
|
||
|
|
time reaches beyond the threshold). Fix this by disabling the workaround
|
||
|
|
(getting the ACK status of NULL func frames by sending via HTT mgmt-tx
|
||
|
|
path) introduced by the change ("ath10k: fix beacon loss handling ")
|
||
|
|
for QCA99X0 and later chipsets. The normal tx path provides the proper
|
||
|
|
ACK status for NULL data frames. As of now disable this workaround for
|
||
|
|
chipsets QCA99X0 and later, once the 10.1 firmware is obselete we can
|
||
|
|
completely get rid of this workaround for all the chipsets
