FS#2053 - Regular crashes of ath10k-ct driver on ZyXEL NBG6817

Good news: OpenWRT 21.02-rc1 appears to have possibly addressed the WiFi driver crash for ZyXEL NBG6817!  I've gotten around 2 weeks of uptime without the same crash.

Bad news: I haven't managed to test for longer because [[https://bugs.openwrt.org/index.php?do=details&task_id=3099|Linux kernel 5.4 appears to have a new crashing bug related to the CPU governor frequency scaling]]; I appear to be getting this bug every time I'm backing up in Deja Dup over OpenSSH chroot'd SFTP (frequently alternating between high CPU and low CPU on the router).  I'm testing the "performance" governor workaround now and I'll either add to that bug report (if related) or file a new one (if this workaround doesn't work).
