From 2c0f5292d5358c2c5576146071d641110c3c1612 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 18 Jun 2020 14:25:06 +0300 Subject: [PATCH] RDMA/mlx5: Remove ECE limitation from the RAW_PACKET QPs Like any other QP type, rely on FW for the RAW_PACKET QPs to decide if ECE is supported or not. This fixes an inability to create RAW_PACKET QPs with latest rdma-core with the ECE support.
