tests: e2e: reduce background traffic noise in chain_update_set

qdeslandes · qdeslandes · commit 0703e671d6c2 · 2026-03-04T00:04:00.000+01:00
chain_update_set.sh uses pings and rule counters to validate sets are
updated as expected. Because the matcher is wide, we sometime fails the
test due to background traffic on the NIC. Limit the rule to the
existing matchers + `ip4.proto icmp` to catch on ping traffic.
