From 707c4602cda6624940761b66a4119f1909492385 Mon Sep 17 00:00:00 2001 From: Majd Dibbiny Date: Thu, 4 Jun 2015 19:30:41 +0300 Subject: net/mlx5_core: Add new query HCA vport commands Added the implementation for the following commands: 1. QUERY_HCA_VPORT_GID 2. QUERY_HCA_VPORT_PKEY 3. QUERY_HCA_VPORT_CONTEXT They will be needed when we move to work with ISSI > 0 in the IB driver too.
