[Make-wifi-fast] beamforming and antenna debugging

[Dave Taht]

It is really good to be completely over my head for a change, to some
extent. From:

https://forum.openwrt.org/t/tuning-beamforming-and-antenna-design/203720

It is very rare these days that I get permission to talk about what I'm
doing, but today I did! Somos Internet has been designing and building
their own MT79 based internet router and bridge for the past few months.
They engaged me to take a look at the reference board, and we were really
pleased to see how well all of OpenWrt, not just the make-wifi-fast
fq_codel bits, was working nowadays.

That was last month. This month, they got back the new boards with a new
antenna layout, and the 5ghz performance at range is *terrible*. I confess
that I no longer have even the slightest grip on how to go about debugging
and improving antenna performance - are there beamforming variables worth
sweeping in the mt76 driver? A piece of test gear we could use to see what
is going wrong? A design tool for antennas? A debugging strategy for
antenna placement?
