Subject: [PATCH net-next 2/5] net: dsa: mv88e6xxx: helper to setup upstream port
Date: Mon, 4 Dec 2017 12:34:54 -0500 [thread overview]
Message-ID: <20171204173457.14873-3-vivien.didelot@savoirfairelinux.com> (raw)
In-Reply-To: <20171204173457.14873-1-vivien.didelot@savoirfairelinux.com>
Add a helper function to setup the upstream port of a given port.
This is the port used to reach the dedicated CPU port. This function
will be extended later to setup the global upstream port as well.
