Subject: [PATCH rdma-next 0/6] Add 800Gb (XDR) speed support

From: Leon Romanovsky <leonro@...dia.com>

Hi,

This series extends RDMA subsystem and mlx5_ib driver to support 800Gb
(XDR) speed which was added to IBTA v1.7 specification.

Thanks

Or Har-Toov (2):
  IB/core: Add support for XDR link speed
  IB/mlx5: Expose XDR speed through MAD

Patrisious Haddad (4):
  IB/mlx5: Add support for 800G_8X lane speed
  IB/mlx5: Rename 400G_8X speed to comply to naming convention
  IB/mlx5: Adjust mlx5 rate mapping to support 800Gb
  RDMA/ipoib: Add support for XDR speed in ethtool
