Florian Westphal 0f1148abb2 selftests: netfilter: add selftest for directional zone support
Add a script to exercise NAT port clash resolution with directional zones.

Add net namespaces that use the same IP address and connect them to a
gateway.

Gateway uses policy routing based on iif/mark and conntrack zones to
isolate the client namespaces.  In server direction, same zone with NAT
to single address is used.

Then, connect to a server from each client netns, using identical
connection id, i.e.  saddr:sport -> daddr:dport.

Expectation is for all connections to succeeed: NAT gatway is
supposed to do port reallocation for each of the (clashing) connections.

This is based on the description/use case provided in the commit message of
deedb59039 ("netfilter: nf_conntrack: add direction support for zones").
