From 6781939054a1a161e06e7a7955a4846be770a711 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Thu, 21 Jan 2021 21:40:37 +0100 Subject: net: mrp: move struct definitions out of uapi None of these are actually used in the kernel/userspace interface - there's a userspace component of implementing MRP, and userspace will need to construct certain frames to put on the wire, but there's no reason the kernel should provide the relevant definitions in a UAPI header. In fact, some of those definitions were broken until previous commit, so only keep the few that are actually referenced in the kernel code, and move them to the br_private_mrp.h header.

Therefore, update the function to be used only with STP port state and use the id SWITCHDEV_ATTR_ID_PORT_STP_STATE. The choice of using STP over MRP is that the drivers already implement SWITCHDEV_ATTR_ID_PORT_STP_STATE and already in SW we update the port STP state.
