Comment 2 for bug 1434158

The code snippet above is in the IPv6 section of _get_snat_idx(), but there is no floating IPv6, and hopefully won't ever be since we really don't require it.

And with DVR, the FIP namespace and rules live on the compute node, but the SNAT namespace and rules live on the network node, so I'm trying to think how they could impact each other, perhaps only on a single-node install (devstack) ?

The 32768 the code is referring to is also a Linux kernel thing, and not related to the FIP rule allocator code.

Have we actually ever seen a problem?
