Summary0016726: mlx4_core driver does not support ConnectX-2 cards
DescriptionThe above kernel module supports Mellanox ConnectX-2 cards by default as long as it is compiled with switch CONFIG_MLX4_CORE_GEN2. As per https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/mellanox/mlx4/Kconfig?h=v5.4-rc7 this is the default setting for recent kernels.

CentOS 8 for some reason disabled this setting and ConnectX-2 cards do not work any longer.

Will make the requested change in the next release of the plus kernel. However any change in the distro kernel must come from upstream (RHEL) .
