From 728b6447e766fc0aaf59e888635d62d54e77a528 Mon Sep 17 00:00:00 2001 From: Alexander Kozyrev Date: Thu, 13 Jan 2022 16:36:09 +0200 Subject: [PATCH] net/mlx5: fix MPRQ WQE size assertion Preparation of the stride size and the number of strides for Multi-Packet RQ was updated recently to accommodate the hardware limitation about minimum WQE size. The wrong assertion was introduced to ensure this limitation is met. Assert that the configured WQE size is not less than the minimum supported size.
