From 0717831143ec348a8df5c8f69944209e8842a0db Mon Sep 17 00:00:00 2001 From: Anuradha Karuppiah Date: Wed, 25 Mar 2020 06:10:54 -0700 Subject: [PATCH] linux: UAPI for MAC sync MAC entries rxed from an ES-peer need to be marked as static to prevent them from being aged out. However, for static entries, we still need to track local activity to independently (independent of BGP) establish that a host is still attached to the ES.
