Mike, Mark, all,
I agree with Mark that there is no explicit requirement that a STA has to be able to receive all possible legal frames successfully. Minimum receive sensitivity requirements imply that STAs have to be able to receive certain lengths (1024 octets, 4096 octets, etc.), and perhaps there are implied requirements to be able to receive lengths that are used in some control frames, but where is the requirement that the receiving STA has to be able to process all frame lengths (or more to the point, all possible frames of all possible lengths) successfully?
I’d describe it as an expectation, rather than a requirement, that receivers have to be able to process valid frames. However, I don’t think it’s helpful to add a note here, and especially not the proposed note, which seems to place the onus on transmitters.
Receivers are not required to process valid frames? What kind of standard is this!? The baseline for interoperability (which is the whole point of doing a standard, right?) is that every valid thing that can be constructed and sent can be received and processed. On top of that we can have requirements to ignore what you don't understand—be conservative in what you send and liberal in what you accept, etc—or drop things that you don't understand or whatever, but if our standard doesn't require that valid frames have to be able to be processed on reception then we have a bigger problem.
Dan.
