The NVIDIA BlueField-2 DPU SoC requires an errata kernel for kdump to pass

Issue

Under kdump environment, mlx5 driver tries to use minimal resources as possible since the RAM is very limited. And when using a device that supports TLS offload (like ConnectX-6 Dx or BlueFiled-2), the stop room will be higher than the SQ size and so the vmcore copy over NFS fails as it won't have a working interface.
