  This patch series introduces hairpin memory configuration options proposed in
http://patches.dpdk.org/project/dpdk/patch/20220811120530.191683-1-dsosnowski@nvidia.com/
for Rx and Tx hairpin queues. It also implements handling of these options in mlx5 PMD
and allows to use new hairpin options in testpmd (through `--hairpin-mode` option) and
flow-perf (through `--hairpin-conf` option).

Dariusz Sosnowski (7):
  ethdev: introduce hairpin memory capabilities
  common/mlx5: add hairpin SQ buffer type capabilities
  common/mlx5: add hairpin RQ buffer type capabilities
  net/mlx5: allow hairpin Tx queue in RTE memory
  net/mlx5: allow hairpin Rx queue in locked memory
  app/testpmd: add hairpin queues memory modes
  app/flow-perf: add hairpin queue memory config

2 things are missing in this series:

1/ motivation (why is this needed)
2/ compilation on Windows
	looks like devx_umem_reg has 5 parameters in Windows glue!

Hi Thomas,

I sent the v2 of the patches.

> 1/ motivation (why is this needed)
I added the feature motivation in the cover letter of v2.

> 2/ compilation on Windows
>         looks like devx_umem_reg has 5 parameters in Windows glue!
Fix for that is included in v2.

Best regards,
Dariusz Sosnowski
