Subject: [PATCH net-next 2/2] net: ethernet: mediatek: support custom GMAC label
Date: Sun, 18 Apr 2021 21:03:52 -0700	[thread overview]
Message-ID: <20210419040352.2452-3-ilya.lipnitskiy@gmail.com> (raw)
In-Reply-To: <20210419040352.2452-1-ilya.lipnitskiy@gmail.com>

The MAC device name can now be set within DTS file instead of always
being "ethX". This is helpful for DSA to clearly label the DSA master
device and distinguish it from DSA slave ports.

For example, some devices, such as the Ubiquiti EdgeRouter X, may have
ports labeled ethX. Labeling the master GMAC with a different prefix
than DSA ports helps with clarity.
