[Alice Mikityanska]

From: Alice Mikityanska <alice@isovalent.com>

Commit 5cb53743e1ff ("selftests: net: Add a test for BIG TCP in UDP
tunnels") used iptables match comment, which was missed from the CI
kernel config. Add the missing config option.

But I think another follow-up patch is required, because this test is
flaky when using a debug kernel config:

Maybe because wait_local_port_listen() is required after having called
netserver?

Cheers,
Matt
