Media-Specific OOB Data for Native 802.11 Send Operations

  • Article

Important  The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.

 

Each packet sent by the 802.11 station through calls to the MiniportSendNetBufferLists function has out-of-band (OOB) data. The OOB data contains media-specific parameters that the 802.11 station uses when transmitting the packet.

The miniport driver accesses the Native 802.11 OOB data through the NET_BUFFER_LIST_INFO macro with the following parameters:

  • The _NBL parameter, which has the pointer to the NET_BUFFER_LIST structure used for the received 802.11 packet.

  • The _ id parameter, which has an identifier (ID) value of MediaSpecificInformation.

The data type for the Native 802.11 media-specific OOB data is the DOT11_EXTSTA_SEND_CONTEXT structure.

In addition to media-specific OOB data, the miniport driver can access IEEE 802.1Q OOB data through the NET_BUFFER_LIST_INFO macro using the following parameters:
