Build Update for ovsrobot/ovn

Build: #1034
Status: Passed

Duration: 19 mins and 53 secs
Commit: 3b0603d (series_203733)
Author: venu iyer
Message: ovn-controller: Check for tunnel change in multi-vtep case is incorrect

Prior to multi-vtep, there was one tunnel for each type, since
there was only one encap-ip. So, the check in
	sset_count(encap_type_set) != encap_type_count
worked. However, with multiple IPs per tunnel type, the above
check won't work. So, once multiple encap-ips are configured,
ovn-controller will always keep updating the encap list in
the SB (due to the above check); this causes a lot of unnecessary
churn, including recomputing the flows etc. which will put
ovn-controller in overdrive thereby consuming lot of CPU cycles
(see almost 100%).

Verified ovn-controller cpu utilization with the fix (and also
that SB doesn't keep constantly updating). make check didn't
show any additional failures.
