enableBeaconEarlyTermination
Beacon early termination feature; allows power
down as soon as TIM bit is clear without waiting
for entire beacon to be received and FCS
checked. Power savings depends on beacon
size and placement of the TIM IE within the
beacon.
For scenario (150-byte beacon and Cisco 1252
AP), active receive duration shrinks from 1.3 ms
to 800 µs with BET enabled

beaconEarlyTerminationWakeInt
erval
For BET, a FCS check is not performed when
TIM is clear; RXP does not update TSF using
timestamp from the beacon.
Can result in drift over time when no traffic for
STA
Periodically and temporarily suspends BET
for a TSF resync by allowing a full beacon to
be received with FCS check and RXP update
of TSF

gEnableBypass11d
Bypass 802.11d; when enabled, start with an

1. AP indicates queued frames for QCA devices by turning on the TIM bit in beacon.
2. QCA device sends data null frame with PM bit set to 0, which implies QCA device is out of
sleep.
3. QCA61x4 starts a software timer with gDataInactivityTimeout value.
4. AP sends the queued frames. The QCA device acknowledges accordingly.
5. When the timer expires, if the QCA devices receives any data frame from AP, it restarts the
timer.
NOTE: If the device receives no data, it sends data null with PM set to 1. This implies it is going to
sleep. If AP has frames for the QCA device, AP queues them until next beacon interval.

gTDLSExternalControl
TDLS external control works with TDLS
implicit trigger. TDLS external control allows
a user to add a MAC address of potential
TDLS peers so that the CLD driver can
initiate implicit TDLS setup to only those
peers when criteria for TDLS setup
(throughput and RSSI threshold) is met.
When TDLS external control is enabled,
CLD driver does not initiate TDLS setup
to a peer if it has not been added
externally, even though traffic towards
that peer meets implicit TDLS criteria
If TDLS connection is initiated from a
peer, the CLD driver accepts the TDLS
connection, even if that peer MAC is not
configured before connection setup
For TDLS external control to work,
supplicant also needs to be configured for
external control
