Did the "master" that you tested include the following commit? It fixed
a number of races in practice.
commit 49d7c759b82e78acd03288c123b1bc0c8904a52b
Author: Ben Pfaff <b...@ovn.org>
Date: Tue Jul 26 23:50:06 2016 -0700
tests: Remove most packet-forwarding related "sleep"s from OVN tests.
These arbitrary sleeps are often longer than necessary and can be too short
in corner cases. This commit replaces them by a common macro that waits
only as long as necessary.
