From c0c1d3d761c32ece93b1c99d200591415e3cbf7c Mon Sep 17 00:00:00 2001 From: Oren Duer Date: Sun, 29 Apr 2012 17:04:24 +0300 Subject: IB/mlx4: Put priority bits in WQE of IBoE MLX QP Otherwise CM packets going over MLX QP1 get fixed scheduling priority 0. We want CM packets to get the same scheduling priority, and therefore map to the same SQ (Schedule Queue) and eventually TC (Traffic Class), as the application requested for the actual QP used for the connection.
