Replacing buffered frame with a new frame (with different length and MCS) #141

Open makesens86 opened 6 years ago

makesens86 commented 6 years ago

Hello?

When an AP is waiting to access channel before its transmission, can a buffered frame be replaced with a new frame with different length and MCS?

For example, let's assume there are 2 A-MPDU frames in the TX buffer, (one is consisting of subframes #1-5, and the other is consisting of subframes 6-10). In this case, is it possible to make new A-MPDU frame with subframe number 1-8?

Right now, I am considering this way. First, flush out all the buffered A-MPDU frames and move all the subframes in the software queue and make a new A-MPDU frame with target length. Is there any other option to recommend? (I am studying the src code related with A-MPDU generation, but still long way to go.. T_T).

Thank you very much.

hi,

once it in the hw tx queue it needs to go out or be aborted and retried.

@erikarn Hi, always appreciate for your comments. If it is aborted, is the original frame (multiple subframes) buffered software queue? I will look into the src code about abort and retry.
