Lorenzo Bianconi 1d6123f87e selftests: netfilter: nft_flowtable.sh: fix offload counter verification for tunnel tests
The IPIP and IP6IP6 tunnel tests call check_counters() to verify
flowtable offloading occurred, but the flow-add rule only matches
meta oif "veth1". When traffic is routed through a tunnel device,
oif is the tunnel interface (tun0, tun6, etc.), not veth1, so
the flow-add rule never fires, no flowtable entry is created,
and counters stay at zero — producing a silent false pass.
Fix by adding tunnel-specific flow-add rules for each tunnel
interface. These match TCP dport 12345 traffic before the bare
accept rule, set ct mark, add the flow to the flowtable, and
increment routed_orig. The existing routed_repl rule on veth0
already handles the reply direction since decapsulated reply
packets exit through the physical interface.
Also add check_counters() for the IP6IP6 non-VLAN and
IP6IP6-over-VLAN tests which previously used a bare PASS message.
