From 569c665150156e44ecbd92af47a6d3fd4e2e4690 Mon Sep 17 00:00:00 2001 From: Danit Goldberg Date: Fri, 30 Nov 2018 13:22:05 +0200 Subject: IB/mlx5: Add packet based credit mode support The device can support two credit modes, message based (default) and packet based. In order to enable packet based mode, the QP should be created with special flag that indicates this. This patch adds support for the new DV QP creation flag that can be used for RC QPs in order to change the credit mode.
