Ipv4 L3ArbitraryBitMask works on OVS but not other switches

The switch should do it fo it self, or the flow sent should be normalized. And the same plugin can't change the information gain from switch when storing to operational DS. Plugin normalizes ipv4arbitrary but only for matching the flows. This was made in the latest code. So even if the switch stores the IP wrong plugin matches the flow.</p> <p>Any thoughts/updates Sai? Should we close this?</p> <p>I think this should fix the issue. <a href="https://git.opendaylight.org/gerrit/#/c/36471/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/36471/</a></p> <p>I haven't checked recently. We can close it for now. </p> Development External issue ID 5562 External issue URL Rank 0|i032fj:
