From 9cde070874b822d4677f4f01fe146991785813b1 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 21 Mar 2007 14:22:44 -0700 Subject: bridge: add support for user mode STP This patchset based on work by Aji_Srinivas@emc.com provides allows spanning tree to be controled from userspace. Like hotplug, it uses call_usermodehelper when spanning tree is enabled so there is no visible API change. If call to start usermode STP fails it falls back to existing kernel STP.
