According to many bugreports [0][1][2] the default ath10k-ct kernel module is unusable on devices with just 64 MiB RAM or with 128 MiB and dual ath10k cards. The target boards boot but eventually oom-killer starts to interfere with normal operation, so the current state is effectively broken. Since the two patches in question have a performance impact (and possibly some other unexpected side-effects) a dedicated build variant is added so that users of the low RAM devices can still benefit from all the ath10k-ct advantages. According to testing [3] results, the issue can be experienced even with "a 256MB device with three radios". Measured performance impact of implementing small buffers was lowering "the maximum 5 GHz throughput on an IPQ40xx device without RPS/XPS optimizations from 494/432 Mbit/s for TCP transfers (download/upload) to 438/343 Mbit/s" The patches were apparently inspired by QSDK tweaks used by ODMs for the affected devices.
