Re: [STDS-802-11-TGBH] CIDs 23, 135 and 224

Thankyou Antonio, for pointing out the need to address the failure cases where Device ID and IRM checks produce different outcomes. The added text still doesn't inform the implementer what behavior is expected. Saying they are not linked still can produce different results, with different potentially conflicting actions. Is the intention that it be implementation specific which is given precedence? Or am I incorrect in thinking there is a conflict in behavior?

Dear all,

as promised during the last AC I am providing new text for the resolution of these CIDs.

Current text agreed during comment resolution for these CIDs is the following:

NOTE: Device ID and IRM are independent schemes that allow an AP to recognize a non-AP STA prior to association and identify it during association respectively. The device ID is allocated by an AP, and the IRM is selected by a non-AP STA. If an AP and a non-AP STA both support both IRM and device ID, the non-AP STA might provide both an IRM and a device ID.

I think this explanation lacks information on how to proceed if both mechanisms while used concurrently yield to different results. In addition, the above paragraph seems to indicate IRM provides identification, while it is not.

I am proposing the following text, let me know what do you think

NOTE: Device ID and IRM are independent schemes that can be used concurrently. The device ID is allocated by an AP, and enables identification of the STA during association. IRM enables an AP to recognize that a STA has been associated previously to the AP, therefore not providing any identification. If an AP and a non-AP STA both support both IRM and device ID, the non-AP STA might provide both an IRM and a device ID. Both mechanisms are not related and their failure or success is not linked.
