So I'm working on tidying up my 11n TX code.

We don't run WDS on our 2.4 GHz APs. We only run WDS on Ubiquiti M5 series in PTP because that's the way they produce a transparent Layer 2 bridge. Is the amount of time spent processing such a request, combined with logging and a busy channel, perhaps enough to effectively cause a denial of service? kind regards/ldv p.s.: I refer implicitly to Sam Leffler's comments last year about the likely sources of stuck beacons.
