Subject: [RFC PATCH v6 03/11] leds: trigger: netdev: drop NETDEV_LED_MODE_LINKUP from mode
Date:   Tue,  3 May 2022 17:16:25 +0200
Message-Id: <20220503151633.18760-4-ansuelsmth@gmail.com>
In-Reply-To: <20220503151633.18760-1-ansuelsmth@gmail.com>

Content-Transfer-Encoding: 8bit
Precedence: bulk

Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool
that will be true or false based on the carrier link. No functional
change intended.
