  This patch set optimizes qede_{rx,tx}_entry and introduces
rte_pktmbuf_free_bulk in qede_process_tx_compl. The overall performance
improvement depends on the use-case; in a physical-virtual-physical test
on a ThunderX2 99xx system with two SMT threads used in ovs,
and two cores used in a vm, an improvement of around 2.55% is observed
due to this patch set.

Changes in v2:
  - Fix checkpatches.sh warnings
  - Fix check-git-log.sh warnings
  - Add Reviewed-by: Igor Russkikh <irusskikh@marvell.com>

Balazs Nemeth (7):
  net/qede: remove flags from Tx entry
  net/qede: get consumer index once
  net/qede: assume mbuf to free is never null
  net/qede: free packets in bulk instead of one by one
  net/qede: prefetch hardware consumer
  net/qede: prefetch next packet to free
  net/qede: remove unnecessary field in Rx entry and simplify
