From bdec9cb83936e0ac4cb87fed5b49fad0175f7dec Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/5] leds: trigger: netdev: Rename add namespace to netdev
trigger enum modes
Rename NETDEV trigger enum modes to a more symbolic name and add a
namespace to them.
Also add __TRIGGER_NETDEV_MAX to identify the max modes of the netdev
trigger.
This is a cleanup to drop the define and no behaviour change are
intended.
