2.2.1.1 microsoft_diagnostics_capability
The microsoft_diagnostics_capability parameter specifies whether a Wi-Fi Display Sink supports including the microsoft_teardown_reason parameter (section 2.2.1.2) in the message body of the M8 request.
The ABNF syntax is as follows:
-
microsoft-diagnostics-capability = "microsoft_diagnostics_capability:" SP diagnostics-capability CRLF diagnostics-capability = "supported" / "none"
If the diagnostics-capability parameter has the value "supported", it means that the M8 request ([WF-DTS2.1] section 6.4.8) that was sent by the Wi-Fi Display Sink includes the microsoft_teardown_reason parameter in the message body of that request. If the diagnostics-capability parameter has the value "none", it means that there are no changes to the M8 request.
