Subject: [PATCH v3 net-next 5/5] dt-bindings: net: dsa: Document dsa-tag-protocol property
Date: Tue, 20 Apr 2021 20:53:11 +0200	[thread overview]
Message-ID: <20210420185311.899183-6-tobias@waldekranz.com> (raw)
In-Reply-To: <20210420185311.899183-1-tobias@waldekranz.com>

The 'dsa-tag-protocol' is used to force a switch tree to use a
particular tag protocol, typically because the Ethernet controller
that it is connected to is not compatible with the default one.
