Hi guys,

	In our ObjectStorage products, we run NVMe_over_RDMA and NVMe_over_TCP traffic through Mellanox ConnectX NICs.

	You know Mellanox has a series of ConnectX NIC models.
E.g., ConnectX-4 Lx, ConnectX-6 Dx, etc.
	And for each NIC model, there is a series of firmware versions.
	E.g., for ConnectX-4 Lx, the available firmware versions include 14.27.1016, 14.28.2006, etc.

	On the other hand, in SLES 15 SP4, the kernel module mlx5_core is the driver of the ConnectX NICs.
	As an alternative, the MLNX_OFED also provides its own implementation of the kernel module mlx5_core.
	For us, in some products, we use the MLNX_OFED, in some products, we use the SLES 15 SP4 inbox drivers.

	However, as I know, in each release of the MLNX_OFED, for each ConnectX NIC model, they always announce
an explicit list of supported firmware versions.
	E.g., in MLNX_OFED 4.9-6.0.6.0-LTS, for ConnectX-4 Lx, the supported firmware versions are 14.27.1016, 14.28.2006.

	So our question is, in case we use SLES 15 SP4 inbox drivers instead of the drivers from the MLNX_OFED, are there any
similar version-matching requirements between kernel module mlx5_core and Mellanox ConnectX NIC firmware.

	If so, for RDMA and TCP/IP, do the version-matching requirements only apply to one of them or both?
