Build Update for ovsrobot/ovn
-------------------------------------

Build: #1057
Status: Passed

Duration: 19 mins and 40 secs
Commit: 4e48476 (series_204220)
Author: venu iyer
Message: 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
chassis_tunnels_changed():

    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.

Fixes: Fixes: b520ca7 ("Support for multiple VTEP in OVN")
