[PATCH v3 00/12] ath11k: optimizations in data path

From: P Praneesh <hidden>
Date: 2021-09-02 05:34:45
Also in: ath11k

This patchset covers optimizations in rx (first 7 patches)
and tx (remaining 5 patches) data path.

Running UDP DL/UL traffic on IPQ8074 5G radio showed an average 5-10%
improvement on a 4 core platform
---
v3:
	- Changed rcu_dereference to rcu_access_pointer in
	  [PATCH 07/12] ath11k: add branch predictors in process_rx
	  [PATCH 11/12] ath11k: add branch predictors in dp_tx path.
	  removed redundant check in
	  [PATCH 02/12] ath11k: allocate dst ring descriptors from
	  cacheable memory.
v2:
        - Addressed internal developer reported segfault and avoid lookup twice
          by utilizing idr_remove (patch 12/12 and patch 2/12).
