Subject: [patch net-next v2 6/6] rocker: use change upper info
From: Jiri Pirko <jiri@...lanox.com>
Since now information about changed upper is passed along, benefit from
that and use this info directly.
This also fixes possible issues that could happen when non-master device
is added (current code does not distinguish between master and non-master
upper device).
