From 4525a45bfad55a00ef218c5fbe5d98a3d8170bf5 Mon Sep 17 00:00:00 2001 From: Huy Nguyen Date: Wed, 28 Dec 2016 14:58:40 +0200 Subject: [PATCH] net/mlx5e: Check ets capability before initializing ets settings During the initial setup, the ets command is sent to firmware without checking if the HCA supports ets. This causes the invalid command error. Add the ets capiblity check before sending firmware command to initialize ets settings.
