Subject: [PATCH net-next 07/16] net: dsa: use ports list to find a port by node
Date: Sat, 19 Oct 2019 23:19:32 -0400	[thread overview]
Message-ID: <20191020031941.3805884-8-vivien.didelot@gmail.com> (raw)
In-Reply-To: <20191020031941.3805884-1-vivien.didelot@gmail.com>

Use the new ports list instead of iterating over switches and their
ports to find a port from a given node.
