Subject: IB/mlx5: Always return success for RoCE modify port
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ec2558796d25e6024071b6bcb8e11392538d57bf;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

IB/mlx5: Always return success for RoCE modify port

CM layer calls ib_modify_port() regardless of the link layer.

For the Ethernet ports, qkey violation and Port capabilities
are meaningless. Therefore, always return success for ib_modify_port
calls on the Ethernet ports.
