From 0c70aa2073addcd16fe94237a4a23314b88bfeb7 Mon Sep 17 00:00:00 2001 From: Alex Wang Date: Thu, 6 Aug 2015 15:40:57 -0700 Subject: [PATCH] ovn-controller-vtep: Extend vtep module to install Ucast_Macs_Remote. This commit extends the vtep module to support creating the 'Ucast_Macs_Remote' table entries in the vtep database for MAC addresses on the ovn logical ports.
