From 91dee144817e51bbfbdc06af4dc1acce6e92bdda Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 26 Oct 2017 11:22:52 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: skip unused ports The unused ports are currently configured in normal mode. This does not prevent the switch from being functional, but it is unnecessary. Skip unused ports. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S.
