[Make-wifi-fast] sophgo risc-v wifi6 chip

[Bob McMahon]

yes, and it could be made in a pluggable form similar to the SFP. The
waveguides and the antenna are "one and done" for a building, can be put
behind walls, 40-80 year lifetime, etc. The part that is changing and
gets deprecated every few years by large amounts of invested NRE is the
Wi-Fi chips themselves. The thing that fails are lasers or optics (that's
part of the reason optics are pluggable in data centers.) So incorporating
Wi-Fi analog & digital and the optics (and optics DSP, if needed) on the
same pluggable, low power, part is a very good form factor. The upgrade
cycle is about every 2 years, for those that want the newer 802.11 features
as that standard continues to evolve.

Also, if pacing/ECN actually works at scale then the Wi-Fi chip is further
simplified, doing L4S marking. The packet stuff can be done in a Fi-Wi
concentrator that is 802.3 frame aware or at the host CCAs and the Wi-Fi
chip need worry about packets (which are an artifact.)  Just be a very good
pacer that marks in a way that Wi-Fi receives 802.11 transmits for a local
optimum, e.g. correlated with the MAC access (EDCA) and the aggregation and
the MCS and possibly bulk vs interactive.
