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

Build: #5672
Status: Errored

Duration: 15 seconds
Commit: b8096d5 (branch-2.7)
Author: Ben Pfaff
Message: odp-util: Avoid reading wrong table in generate_all_wildcard_mask().

These lines of code are intended to copy the 'next' and 'next_max' members
of tbl[type] into local variables 'tbl' and 'max':
            tbl = tbl[type].next;
            max = tbl[type].next_max;
They didn't do it properly because the first line changes 'tbl', so that
the first and seconds lines' references to tbl[type] refer to different
objects.

This commit fixes the problem.
