FS#2651 - Out of memory errors with 5 GHz Wi-Fi enabled

- Device problem occurs on Archer C60 V2
- Software versions: Powered by LuCI Master (git-19.337.71995-796301a) / OpenWrt SNAPSHOT r11618-416d2cc71e

I’ve installed via TFTP “openwrt-19.07.0-rc2-ath79-generic-tplink_archer-c60-v2-squashfs-factory.bin” but because of some “out of memory” errors, i’ve upgraded to “openwrt-ath79-generic-tplink_archer-c60-v2-squashfs-sysupgrade.bin” in the hope of solving.
The problems continued, so i wrote to forum (https://forum.openwrt.org/t/tp-link-archer-c60-v2-19-07-0-rc2-ath79-snapshot-out-of-memory/49725) and i saw that other users had the same problem that they solved by disabling 5 Ghz.
Disabling the 5Ghz actually “out of memory” problems disappear. I was also able to install additional packages without problem.

Try with stock driver and firmware instead of CT. This should reduce the impact on memory. However, it fear ath10k is problematic with any driver on this device.

Please try the 19.07.0 release, it introduced a "small buffers" variant kmod-ath10k-ct-smallbuffers for this device.

From my experience, OOM has become rare with ath10k and ath10k-ct-smallbuffers, but for the C60 it never really became stable for a long time or for many clients.

However, I don't see a way to improve this situation at the moment.
