Revert "API cleanup: tap" and bump stable_vpp
The VPP change got a temporary -1, as other change has higher priority. Bumping stable VPP version, so this passes verify right away. This reverts commit ae62a4348f7de53cfb91a5ae25a10723d5f9b398. Change-Id: If2813b0e41451a3a9e7f8b1512521cf508ac92c7 Signed-off-by: Vratko Polak <vrpolak@cisco.com>
