IB/mlx5: Fix mapping of link-mode to IB width and speed
Add mapping of link mode: CAUI4 100Gbps CR4/KR4 with 4 lines and 25Gbps. Fix mapping of link mode: GAUI2 50Gbps CR2/KR2 to be 2 lines with 25Gbps. Fixes: 08e8676f1607 ("IB/mlx5: Add support for 50Gbps per lane link modes") Signed-off-by: Aya Levin <ayal@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
