Subject: [RFC PATCH net-next 06/12] net: dsa: only bring down user ports assigned to a given DSA master
Date: Mon, 23 May 2022 13:42:50 +0300 [thread overview]
Message-ID: <20220523104256.3556016-7-olteanv@gmail.com> (raw)
In-Reply-To: <20220523104256.3556016-1-olteanv@gmail.com>
From: Vladimir Oltean <vladimir.oltean@nxp.com>
This is an adaptation of commit c0a8a9c27493 ("net: dsa: automatically
bring user ports down when master goes down") for multiple DSA masters.
When a DSA master goes down, only the user ports under its control
should go down too, the others can still send/receive traffic.
