Build Update for openvswitch/ovs
-------------------------------------

Build: #5666
Status: Errored

Duration: 9 minutes and 16 seconds
Commit: 51df0ef (branch-2.5)
Author: Yifeng Sun
Message: bond: Fix bug that writes to freed memory

pr_op->pr_rule is pointing to memory in bond->hash. It shouldn't be written
if bond->hash is already freed.

This bug is reported by running kernel path testsuite under valgrind:
