selftests: nft_nat: ensuring the listening side is up before starting the client
The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.
Before the fix:
# ./nft_nat.sh
PASS: netns routing/connectivity: ns0-rthlYrBU can reach ns1-rthlYrBU and ns2-rthlYrBU
PASS: ping to ns1-rthlYrBU was ip NATted to ns2-rthlYrBU
PASS: ping to ns1-rthlYrBU OK after ip nat output chain flush
PASS: ipv6 ping to ns1-rthlYrBU was ip6 NATted to ns2-rthlYrBU
