From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 25 Dec 2021 04:07:05 +0100 Subject: net: stmmac: dwmac-meson: Rename the SPEED_100 macro The SPEED_100 macro is part of the PREG_ETHERNET_ADDR0 register. Rename it accordingly to make this relationship clear. While here also add a comment what the SPEED_100 bit actually does.
