This topic is part of the WiFiCx driver model. WiFiCx is the Wi-Fi driver model released in Windows 11. We recommend that you use WiFiCx to take advantage of the latest features. The previous Wi-Fi driver model WDI is in maintenance mode and will only receive high priority fixes.
WDI_TLV_CONFIGURED_CIPHER_KEY is a TLV that contains a list of configured ciphers to be set in OID_WDI_GET_PM_PROTOCOL_OFFLOAD. Drivers must return any GTK or iGTK keys that are currently configured. This TLV is a value of the WDI_TLV_PM_PROTOCOL_OFFLOAD_80211RSN_REKEY TLV.
TLV Type
0x147
Length
The size (in bytes) of the following values.
