Comment 25 for bug 1731595

SRU addendum for mitaka (xenial) and newton.

[Regression Potential]

For mitaka (xenial) and newton, the regression potential is a little higher than that of ocata+ as the patch(es) aren't available on the corresponding upstream branches (they're EOL). These patches were cherry picked from the upstream stable/ocata branch, and required slight modifications in order to apply to mitaka and newton. For mitaka, an additional patch was required as a pre-req (set-ha-network-port-to-down-when-l3-agent-starts.patch). This patch is already in the upstream branches and packages for newton+.
