Nice. Well never thought about mpls but it seems possible too. With mpls
enabled it seems send something my tcpdump does not understand so I trust
you there. I and it does not seem to brake standard ipv4 sending. So it
should be OK.
But I'll guess the mpls result code is not what you expected...
echo "mpls 0001000a,0002000a,0000000a" > /proc/net/pktgen/eth1
cat /proc/net/pktgen/eth1 | grep Res
Result: 0000000a
sprintf(pg_result, "OK: mpls=");
for(n = 0; n < pkt_dev->nr_labels; n++)
sprintf(pg_result, "%08x%s", ntohl(pkt_dev->labels[n]),
n == pkt_dev->nr_labels-1 ? "" : ",");
Cheers.
