[Make-wifi-fast] bloat on wifi8 and 802.11 wg

[Bob McMahon]

There is a lot of confusion on the 802.11 latency technology options. I
think waiting for Wi-Fi 8 to solve this is a non starter. Solutions have to
work for 20B devices already in the field.

The silo'ing hasn't helped here. Those that cross the silos are needed by
my judgment. It means deep dives into 802.11 which now is a 25 year old set
of standards. Those with 25 years of 802.11 standards expertise are as rare
as hen's teeth and are worth their weight in gold.
