From bd00632c5294bff0ed5826677cd2f1b2e303a6f6 Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Wed, 15 Feb 2017 10:46:40 +0100 Subject: [PATCH] net: stmmac: use SPEED_UNKNOWN/DUPLEX_UNKNOWN It is better to use DUPLEX_UNKNOWN instead of just "-1". Using 0 for an invalid speed is bad since 0 is a valid value for speed. So this patch replace 0 by SPEED_UNKNOWN.
