From 39ae0a07ac17640a7f8ba136eaaf334bfd504030 Mon Sep 17 00:00:00 2001 From: IJsbrand Wijnands Date: Thu, 5 Mar 2020 10:56:26 -0800 Subject: mpls: add user defined name tag to mpls tunnels This allows a user creating MPLS tunnel through the bin_api to add a name tag. This is useful to correlate the Tunnel with its use-case. Also useful if the user needs to recover the MPLS Tunnel after a restart (mark-sweep).
