From fb585b44383c4cff85f92e67377ee1c5f07d6dc1 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Fri, 10 Feb 2017 16:43:50 +0100 Subject: [PATCH] net: make net_device members garp_port and mrp_port conditional garp_port is only used in net/802/garp.c which is only compiled with CONFIG_GARP enabled. Same goes for mrp_port which is only used in net/802/mrp.c with CONFIG_MRP enabled. Only include the two members in struct net_device if their respective CONFIG_* is enabled. This saves a few bytes in struct net_device in case CONFIG_GARP or CONFIG_MRP are not enabled. Signed-off-by: Tobias Klauser Signed-off-by: David S.
