Increase the RXDMA buffer ring size to 8192 entries for the default memory profile to provide additional RX buffering and improve RX packet processing efficiency. This increases memory consumption by approximately 9-10 MiB and improves RX throughput by ~20% with the default memory profile (ATH12K_QMI_MEMORY_MODE_DEFAULT).
