Subject: [PATCH net 05/11] selftests: nft_nat: Simplify port shadow notrack test

From: Phil Sutter <phil@....cc>

The second rule in prerouting chain was probably a leftover: The router
listens on veth0, so not tracking connections via that interface is
sufficient. Likewise, the rule in output chain can be limited to that
interface as well.
