Message-Id: <1477058843-9981-7-git-send-email-jiri@resnulli.us>

Subject: [patch net-next 6/6] mlxsw: Convert resources into array
From: Jiri Pirko <jiri@...lanox.com>
Since the number of resources is going to get much bigger, ease up the
addition by simly defining IDs. Convert the existing structure members
to a set array, one for validity, one for values. Introduce a set of
getters and setters for easy access.
