Basically Xtables-addons's copy of ipset is already functionally equal
to ipset 4.3 thanks to our compat_xtables layer (and our modifications
in ipset/ to use it).
Moving from ipset 2.4.5 to 2.4.7. Upstream changed, but
the Xtables-addons copy did not (issues were not present):
>2.4.7
> - Typo which broke compilation with kernels < 2.6.28
> fixed (reported by Richard Lucassen, Danny Rawlins)
>
>2.4.6
> - Compatibility fix for kernels >= 2.6.28
