Just removing the over-strict check in mlx5 PMD is enough for everything to work fine: https://gerrit.fd.io/r/c/vpp/+/26152/1/build/external/patches/dpdk_20.02/0002-mlx5-azure-workaround.patch > The link speed is unknown but this is not issue, and link state and other link info are correctly reported. > Thomas, any input regarding this behavior in mlx5 PMD? I am not aware about the lack of link speed info. It is probably not specific to ConnectX-4 Lx. I guess it happens only with Hyper-V? Cc mlx5 maintainers
