Subject: [pull request][net-next 00/15] mlx5 updates 2020-12-01

Hi Jakub,

This series adds port tx timestamping support and some misc updates.
For more information please see tag log below.

Please pull and let me know if there is any problem.

Please note that the series starts with a merge of mlx5-next branch,
to resolve and avoid dependency with rdma tree.

Thanks,
Saeed.

  net/mlx5e: Fill mlx5e_create_cq_param in a function (2020-12-01 14:25:16 -0800)

----------------------------------------------------------------
mlx5-updates-2020-12-01

mlx5e port TX timestamping support and MISC updates

1) Add support for port TX timestamping, for better PTP accuracy.

Currently in mlx5 HW TX timestamping is done on CQE (TX completion)
generation, which much earlier than when the packet actually goes out to
the wire, in this series Eran implements the option to do timestamping on
the port using a special SQ (Send Queue), such Send Queue will generate 2
CQEs (TX completions), the original one and a new one when the packet
leaves the port, due to the nature of this special handling, such mechanism
is an opt-in only and it is off by default to avoid any performance
degradation on normal traffic flows.

2) Misc updates and trivial improvements.
