Message

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.

P Praneesh (12):
  ath11k: disable unused CE8 interrupts for ipq8074
  ath11k: allocate dst ring descriptors from cacheable memory
  ath11k: modify dp_rx desc access wrapper calls inline
  ath11k: avoid additional access to ath11k_hal_srng_dst_num_free
  ath11k: avoid active pdev check for each msdu
  ath11k: remove usage quota while processing rx packets
  ath11k: add branch predictors in process_rx
  ath11k: allocate HAL_WBM2SW_RELEASE ring from cacheable memory
  ath11k: remove mod operator in dst ring processing
  ath11k: avoid while loop in ring selection of tx completion interrupt
  ath11k: add branch predictors in dp_tx path
  ath11k: avoid unnecessary lock contention in tx_completion path
