ath10k: optimize ce_lock on post rx buffer processing After processing received packets from copy engine, host will allocate new buffer and queue them back to copy engine ring for further packet reception. On post rx processing path, skb allocation and dma mapping are unnecessarily handled within ce_lock. This is affecting peak throughput and also causing more CPU consumption. Optimize this by acquiring ce_lock only when accessing copy engine ring and moving skb allocation out of ce_lock. In AP148 platform with QCA99x0 in conducted environment, UDP uplink peak throughput is improved from ~1320 Mbps to ~1450 Mbps and TCP uplink peak throughput is increased from ~1240 Mbps (70% host CPU load) to ~1300 Mbps (71% CPU load). Similarly ~40Mbps improvement is observed in downlink path. Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
