From 6b297524234ccf3954b54609ab6bc2e8c4d3f677 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Fri, 25 Oct 2019 01:03:51 +0200 Subject: net: dsa: Add support for devlink device parameters Add plumbing to allow DSA drivers to register parameters with devlink. To keep with the abstraction, the DSA drivers pass the ds structure to these helpers, and the DSA core then translates that to the devlink structure associated to the device.
