Build Update for ovsrobot/ovs

Build: #2871
Status: Passed

Duration: 1 hr, 4 mins, and 48 secs
Commit: 536734d (series_192595)

Message: odp-util: Fix clearing match mask if set action is partially unnecessary.

While committing set() actions, commit() could wildcard all the fields
that are same in match key and in the set action.  This leads to
situation where mask after commit could actually contain less bits
than it was before.  And if set action was partially committed, all
the fields that was the same will be cleared out from the matching key
resulting in the incorrect flow.

For example, for the flow that matches on both src and dst mac
addresses, if the dst mac is the same and only src should be changed
by the set() action, destination address will be wildcarded in the
match key and will never be matched, i.e. flows with any destination
mac will match, which is not correct.

Fix that by updating matching mask only if mask was expanded, but
not in other cases.

The code before commit dbf4a92800d0 was not able to reduce the mask,
it was only possible to expand it to exact match, so it was OK to
update original matching mask with the new value in all cases.

Fixes: dbf4a92800d0 ("odp-util: Do not rewrite fields with the same values as matched")
