Florian Westphal a2acf0c0e2 selftests: nft_nat: switch port shadow test cases to socat
There are now at least three distinct flavours of netcat/nc tool:
'original' version, one version ported from openbsd and nmap-ncat.

The script only works with original because it sets SOREUSEPORT option.

Other nc versions return 'port already in use' error and port shadow test fails:

PASS: inet IPv6 redirection for ns2-hMHcaRvx
nc: bind failed: Address already in use
ERROR: portshadow test default: got reply from "ROUTER", not CLIENT as intended

Switch to socat instead.
