====================
IPVS Fixes for v4.12

please consider this fix to IPVS for v4.12.

* It is a fix from Julian Anastasov to only SNAT SNAT packet replies only for
  NATed connections

My understanding is that this fix is appropriate for 4.9.25, 4.10.13, 4.11
as well as the nf tree. Julian has separately posted backports for other
-stable kernels; please see:

* [PATCH 3.2.88,3.4.113 -stable 1/3] ipvs: SNAT packet replies only for
        NATed connections
* [PATCH 3.10.105,3.12.73,3.16.43,4.1.39 -stable 2/3] ipvs: SNAT packet
        replies only for NATed connections
* [PATCH 4.4.65 -stable 3/3] ipvs: SNAT packet replies only for NATed
        connections
