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

Build: #3735
Status: Passed

Duration: 12 mins and 14 secs
Commit: f6bfccc (series_237346)
Author: Ilya Maximets
Message: dpif: Fix use of uninitialized execute hash.

'dpif_execute_helper_cb' doesn't initilalize the 'hash' field that
may be passed down to datapath and might cause execution of a different
set of actions, e.g. on recirculation.

 Thread 6 handler27:
 Conditional jump or move depends on uninitialised value(s)
