Subject: [PATCH 7/8] net/mlx5: Properly convey driver version to firmware
Git-commit: 907af0f0cab4ee5d5604f182ecec2c5b5119d294
References: git-fixes
Patch-mainline: v5.11-rc1
mlx5 firmware expects driver version in specific format X.X.X, so
make it always correct and based on real kernel version aligned with
the driver.
Fixes: 012e50e109fd ("net/mlx5: Set driver version into firmware")
