[PATCH net-next 00/16] mlx5 xsk updates part2 2022-09-28

[Saeed Mahameed <saeed@kernel.org>]

From: Saeed Mahameed <saeedm@nvidia.com>

XSK buffer improvements, This is part #2 of 4 parts series.

 1) Expose xsk min chunk size to drivers, to allow the driver to adjust to a
   better buffer stride size

 2) Adjust MTT page size to the XSK frame size, to avoid umem overrun in
  certain situations.

 3) Use xsk frame size as the striding RQ page size for XSK RQs

 4) KSM for unaligned XSK, KSM allows arbitrary buffer chunk lengths
    registration in HW, which makes more sense for unaligned XSK.

 4) More cleanups and optimizations in preparation for next improvements
    in part3

Thanks,
Saeed.
