Description Min Max Default gTxBFEnable Enable/disable Tx beam forming 0 1 0 gTxBFCsnValue Certain TxBF capability APs have an issue: When pronto advertises the CSN value as 3, it uses the 2 antenna in the NDPA packet, but is supposed to use the 3 antenna in the NDPA packet. If the CSN value is advertised as 2, it uses 3 antennas in the NDPA packet. INI configuration is needed for setting the CSN value. 0 3 2 gVhtChannelWidth Channel width for VHT mode: 1 − 20 MHz and 40 MHz 2 – 80 MHz 0 2 2 gVhtRxMCS VHT Rx MCS values: Valid values are 0, 1, 2. If commented out, the default value is 0. 0=MCS0-7 1=MCS0-8 2=MCS0-9 0 2 0 gVhtTxMCS VHT Tx MCS values: Valid values are 0, 1, 2. If commented out, the default value is 0. 0=MCS0-7 1=MCS0-8 2=MCS0-9 0 2 0 gDisableLDPCWithTxbfAP Disable the LDPC when the AP is TxBF-capable. This is a workaround for a throughput issue from the AP test firmware. 0 1 1 gPNOScanSupport Advertise PNO driver capability: 0 − Disable driver PNO capability 1 − Enable driver PNO capability 1 0 1 gPNOScanTimerRepeatValue The driver gets only one timer interval, which is hard-coded in the supplicant for 10000 ms. Until the PNO is disabled, the firmware repeats the PNO scan every 10 sec. Taking power consumption into account, 6 timers will be used; the timer value is increased exponentially, i.e., to 10, 20, 40, 80,160, 320 sec. The number of scan cycles for each timer is configurable through INI parameter gPNOScanTimerRepeatValue. If it is set to 0, only one timer will be used and the PNO scan cycle will be repeated after each interval specified by the supplicant until PNO is disabled. 6 0 0xffffffff gRoamingTime CSR roaming enable (1), disable (0) 0 4294967 UL 10 gEnableFastRoamIn Concurrency Enable legacy fast roaming (LFR) on the STA link during concurrent sessions. 0 1 1 gRssiFilterPeriod Increased this value for the non-CCX AP. This is caused by firmware RSSI monitoring the consumer of this value that is on by default. To impact power numbers this is set to a high value. 0 255 5 gImmediateRoamRssiDiff RSSI delta to allow STA to immediately roam to a qualified AP without registering for the reassociation threshold. A value of 0 means to do an immediate roam if any qualified AP is found from scanning. 0 125 0 80-Y0476-5 Rev.

To enable, set gRoamIntraBand=1 (roaming within band). 0 1 0 FastTransitionEnabled This flag controls fast transition in case of 11r and CCX. With this the whole neighbor roam, pre-authorization, reassociation can be turned on or off. With this turned off, 11r will not work. For 11r, this flag has to be on. For CCX, fast roam will not work. 0 1 0 RoamRssiDiff This parameter is used to decide whether to roam. AP1 is the currently associated AP and AP2 is chosen for roaming. The roaming will occur only if AP2 has a better signal quality and it has an RSSI better than AP1 in terms of RoamRssiDiff and RoamRssiDiff is the number of units (typically measured in dB), and AP2 is better than AP1. This check is not done if the value is zero. Check whether the AP to which you are roaming is better than current AP in terms of RSSI. Checking is disabled if set to zero. Otherwise, it will use this value to determine to how much better the RSSI of the new/roamable AP should be for roaming. 0 30 5 gWESModeEnabled This parameter is used to set Wireless Extended Security Mode, if defined as (WLAN_FEATURE_VOWIFI_11R) || defined (FEATURE_WLAN_CCX) || defined (FEATURE_WLAN_LFR). 0 1 0 gRoamScanNProbes If defined as (WLAN_FEATURE_VOWIFI_11R) || defined (FEATURE_WLAN_CCX) || defined (FEATURE_WLAN_LFR). 1 10 2 gRoamScanHomeAwayTime To determine the time between consecutive channel scans, if defined as (WLAN_FEATURE_VOWIFI_11R) || defined (FEATURE_WLAN_CCX) || defined (FEATURE_WLAN_LFR). 3 300 3 FastRoamEnabled Enable/disable legacy (non-CCX, non-802.11r) Fast Roaming Support. 0 1 0 gRrmEnable 80-Y0476-5 Rev.

With BET, since no FCS check is done when TIM is seen as being clear, RXP does not update the TSF using the timestamp from the beacon. This can lead to drift over time when no traffic for STA. This configuration periodically and temporarily suspends BET in order to allow a TSF re-sync by allowing a full beacon to be received with FCS check and RXP update of TSF. 2 255 3 McastBcastFilter Flags to filter Multicast and Broadcast Rx packets Values: 0 − No filtering 1 − Filter all Multicast 2 − Filter all Broadcast 3 − Filter all Multicast and Broadcast 0 3 0 gTelescopicBeaconWakeupEn Enable/disable Telescopic DTIM feature.

The Roaming will happen only if AP2 has better Signal Quality and it has a RSSI better than AP1 in terms of RoamRssiDiff,and RoamRssiDiff is the number of units (typically measured in dB) AP2 is better than AP1. This check is not done if the value is Zero. Check if the AP to which we are roaming is better than current AP in terms of RSSI. Checking is disabled if set to Zero.Otherwise it will use this value as to how better the RSSI of the new/roamable AP should be for roaming. 0 30 5 gWESModeEnabled This parameter is used to set Wireless Extended Security Mode, if defined (WLAN_FEATURE_VOWIFI_11R) || defined (FEATURE_WLAN_CCX) || defined(FEATURE_WLAN_LFR) 0 1 0 gRoamScanNProbes if defined (WLAN_FEATURE_VOWIFI_11R) || defined (FEATURE_WLAN_CCX) || defined(FEATURE_WLAN_LFR) 1 10 2 gRoamScanHomeAwayTime To determine the time between consecutive channel scans, if defined (WLAN_FEATURE_VOWIFI_11R) || defined (FEATURE_WLAN_CCX) || defined(FEATURE_WLAN_LFR) 3 300 3 FastRoamEnabled Enable/Disable Legacy (non-CCX, non-802.11r) Fast Roaming Support ifdef FEATURE_WLAN_LFR 0 1 0 MAWCEnabled Enable/Disable MAWC (Motion Added Wi-Fi Connectivity) feature 0 1 0 gRoamScanOffloadEnabled Enable/Disable Roam Scan Offload ifdef WLAN_FEATURE_ROAM_SCAN_OFFLOAD 0 1 1 CcxEnabled Enable/Disable CCX feature 0 1 0 InfraInactivityInterval Setting inactivity interval for AddTspec communication 0 429496729 5UL 0 ImplicitQosIsEnabled Enable/Disable driver to initiate ADDTS REQ/RSP to get traffic stream admitted to AP in case phone is trying to transmit an AC frame which has ACM set by AP 0 1 1 gRetryLimitZero Primary rate of maximum retransmission number 0 15 5 gRetryLimitOne Secondary rate of maximum retransmission number 0 15 10 80-Y0476-5 Rev.
