From 278d436a476f69fc95d5c82bf61b6c2d02f4d44e Mon Sep 17 00:00:00 2001 From: Ivan Vecera <ivecera@redhat.com> Date: Mon, 8 Sep 2014 18:46:53 +0200 Subject: [PATCH] net/mlx4_en: do not ignore autoneg in mlx4_en_set_pauseparam() The driver does not support pause autonegotiation so it should return -EINVAL when the function is called with non-zero autoneg.
