From 4de6580360867d44adecb2d05febed1c8d186c82 Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 7 Nov 2013 15:25:14 +0200 Subject: mlx4_core: Add support for steerable IB UD QPs This patch adds support for allocating IB UD QPs that we can steer traffic from. We introduce a new firmware command FLOW_STEERING_IB_UC_QP_RANGE and a capability bit. This command isn't supported for VFs.
