From ec2558796d25e6024071b6bcb8e11392538d57bf Mon Sep 17 00:00:00 2001 From: Majd Dibbiny Date: Wed, 23 Aug 2017 08:35:42 +0300 Subject: [PATCH] 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.
