From 08265ef6179e82ca70d5712223d568f725f371fb Mon Sep 17 00:00:00 2001 From: Luigi Rizzo Date: Fri, 15 Nov 2019 12:12:25 -0800 Subject: [PATCH] net/mlx4_en: fix mlx4 ethtool -N insertion [ Upstream commit 34e59836565e36fade1464e054a3551c1a0364be ] ethtool expects ETHTOOL_GRXCLSRLALL to set ethtool_rxnfc->data with the total number of entries in the rx classifier table. Surprisingly, mlx4 is missing this part (in principle ethtool could still move forward and try the insert).
