I'm glad this is getting some attention and others are chiming in. But
let me tell
you first, that I'm not an opponent of the "American way", I'm trying
to make sense
of it though and also what would happen to the ath10k GPIO patches that got
quietly dropped from your reply there...

As for the "These are wifi/network testing equipment, not network devices."
True and If you are interested you can buy cheaper devices like
<https://www.candelatech.com/ct314_product.php> from the company as well:

"The CT314 is a low-power and affordable applicance with a single 10/100
Ethernet port and one Broadcome 802.11b/g/n Wireless interface. It is targeted
at users who wish to have an inexpensive appliance that can be left at remote
sites for network monitoring and lower speed testing. The maximum throughput
is about 90Mbps bi-directional wired. Wireless throughput is steady at 38Mbps
and can peak at 48Mpbs. The CT314 is based on the Raspberry PI B version 3
platform, running the Ubuntu Server OS. [...]".

I know these have not much to do with the issue at hand ("low-memory system"
support in ath10k(-ct) with OpenWrt). But as Ben explained in the follow-up that
he has a keen interest for supporting the ath10k-ct driver+firmware
and he's doing
a great job with the ath10k-ct issue tracker.
