NDIS_STATUS_WDI_INDICATION_SECONDARY_STA_CONNECTIVITY (dot11wificxintf.h)
WiFiCx drivers use NDIS_STATUS_WDI_INDICATION_SECONDARY_STA_CONNECTIVITY to notify the OS when a secondary STA connection will no longer be usable and when it will be usable again.
When secondary STA connectivity is supported, the driver is required to prioritize Wi-Fi Direct (WFD) connections over secondary STA connections at all times. Therefore if the driver is unable to sustain both connections at the same time, it must send the WDI_INDICATION_SECONDARY_STA_CONNECTIVITY indication with WDI_TLV_LIMITED_CONNECTIVITY set to TRUE. When the secondary STA can be connected again without compromising WFD connectivity, the driver must send the WDI_INDICATION_SECONDARY_STA_CONNECTIVITY indication with WDI_TLV_LIMITED_CONNECTIVITY set to FALSE.
Note
If the driver indicates WDI_INDICATION_SECONDARY_STA_CONNECTIVITY with WDI_TLV_LIMITED_CONNECTIVITY set to TRUE, it may also include an optional list of Band/Channels in WDI_TLV_SECONDARY_STA_BAND_CHANNEL to indicate which band/channels (if any) the OS can use for secondary STA connections.

Payload data
| Type | Multiple TLV instances allowed | Optional | Description |
|---|---|---|---|
| WDI_TLV_LIMITED_CONNECTIVITY | Specifies whether the driver can maintain a secondary STA connection. If this value is 1, the driver cannot maintain a secondary STA connection. Otherwise this value is 0. | ||
| WDI_TLV_SECONDARY_STA_BAND_CHANNEL | X | X | When WDI_TLV_LIMITED_CONNECTIVITY is 1, the driver can include a list of band IDs and optional channel numbers that are available for secondary STA connection. |
