Based on:1ac627024d("kernel: ath10k-ct: provide a build variant for small RAM devices") Like described in the ath10k-ct-smallbuffers version, oom-killer gets triggered frequently by devices with small RAM. That change is necessary for many community mesh networks which use ath10k based devices with too little RAM. The -ct driver has been proven unstable if used with 11s meshing and only wave2 chipsets are supporting 11s. Freifunk Berlin is nowadays assembling its firmware-based completely of vanilla OpenWRT with some package additions which are made through the imagebuilder. Therefore we cannot take the approach other freifunk communities have taken to maintain that patch downstream [1]. Other communities consider these devices as broken and that change would pretty much give those devices a second life [2].
