Build Update for ovsrobot/ovs
-------------------------------------

Build: #3734
Status: Passed

Duration: 12 mins and 15 secs
Commit: c97dd15 (series_237346)
Author: Ilya Maximets
Message: odp-util: Fix use of uninitialized erspan metadata.

'struct erspan_metadata' contains union with fields of different
sizes, hence not all the memory initiliazed.  This memory goes
to syscalls and also used to compare ukeys with memcmp which may
cause unexpected behavior.

 Thread 15 revalidator13:
 Conditional jump or move depends on uninitialised value(s)
