	Ah, good to know; but just out of curiosity is any of the following 7 Byte Preamble + 1 Byte start of frame delimiter (SFD) + 12 Byte inter frame gap (IFG) actually packaged into ethernet frames inside 802.11 packets? I would have guessed that at least the IFG would be dropped as it does not really exist as "data"?
	I realise that for the intended purpose of airtime fairness over-estinating the overhead is more benign than under-estimating it, so I really only am curious about what ends up on the wifi packets data payload.

Best Regards

P.S.: I shortened the CC list, as I am sure the interest in the extent of my lack of knowledge is limited...
