Hi Keith, Thanks for fixing my macros from ETHER_TYPE_IPv6 to PG_ETHER_TYPE_IPv6 in your latest commit.
I tested the 'dev' branch with tap interfaces running the command: `pktgen l 1-5 -n 4 --proc-type auto --log-level debug --file-prefix pg --vdev=net_tap0 --vdev=net_tap1 -- -T -P -m [2:3].0 -m [4:5].1` When I use the latest commit, pktgen crashes. When I go back 1 commit to my changes (manually fixing the ether type macros), my IPv6 changes do work as expected running the same command. Here is the error I saw: Initialize Port 0 -- TxQ 1, RxQ 1 Src MAC 5a:d7:d5:38:f8:a7 <Promiscuous mode Enabled> Initialize Port 1 -- TxQ 1, RxQ 1 !PANIC!: Cannot create mbuf pool (Default TX 1:0) port 1, queue 0, nb_mbufs 16384, socket_id 0: Cannot allocate memory PANIC in pktgen_mbuf_pool_create(): Cannot create mbuf pool (Default TX 1:0) port 1, queue 0, nb_mbufs 16384, socket_id 0: Cannot allocate memory 6: [/home/frankli1/pktgen-dpdk/app/x86_64-native-linuxapp-gcc/app/pktgen() [0x53b853]] 5: [/lib64/libc.so.6(__libc_start_main+0xf5) [0x7fc787ed73d5]] 4: [/home/frankli1/pktgen-dpdk/app/x86_64-native-linuxapp-gcc/app/pktgen(main+0xf03) [0x4977f3]] 3: [/home/frankli1/pktgen-dpdk/app/x86_64-native-linuxapp-gcc/app/pktgen(pktgen_config_ports+0x1d02) [0x567832]] 2: [/home/frankli1/pktgen-dpdk/app/x86_64-native-linuxapp-gcc/app/pktgen(__rte_panic+0xb8) [0x488bf2]] 1: [/home/frankli1/pktgen-dpdk/app/x86_64-native-linuxapp-gcc/app/pktgen(rte_dump_stack+0x16) [0x667ca6]] I haven't tried running pktgen with any other options, and I do believe my changes are incorporated properly, just wanted to bring this error to your attention in case it may be helpful for you.
