From: Meir Lichtinger Date: Mon, 26 Oct 2020 13:37:38 +0000 (+0200) Subject: IB/mlx5: Add support for NDR link speed X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f946e45f59ef01ff54ffb3b1eba3a8e7915e7326;p=linux.git IB/mlx5: Add support for NDR link speed The IBTA specification has new speed - NDR. That speed supports signaling rate of 100Gb. mlx5 IB driver translates link modes reported by ConnectX device to IB speed and width. Added translation of new 100Gb, 200Gb and 400Gb link modes to NDR IB type and width of x1, x2 or x4 respectively.
