On the device I am testing, it is both (2GHz) ath9k and (5GHz) ath10k.
  These look to be related patches to this issue:

960-0010-ath10k-limit-htt-rx-ring-size.patch
960-0011-ath10k-limit-pci-buffer-size.patch

In the v19.07.0-rc2 build for the rb-nor-flash-16M-ac ar71xx image,
these patches are applied to backports-4.19.85-1, but don't seem to be
applied to ath10k-ct-2019-09-09-5e8cd86f.    Should ath10k-ct have
these and other patches?    The device's installed packages do include
ath10k-ct (from downloads.openwrt.org installed image).
