From c8b098086b4c744084350d2757a637ad756adf34 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 4 Jun 2016 21:16:57 +0200 Subject: [PATCH] net: dsa: Add a ports structure and use it in the switch structure There are going to be more per-port members added to the switch structure. So add a port structure and move the netdev into it. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli Reviewed-by: Vivien Didelot Signed-off-by: David S.
