./app/app/x86_64-native-linuxapp-gcc/pktgen -c 0x7 -n 3 --proc-type auto --socket-mem 1024,1024 --no-shconf -w 0000:0a:0a.0 --file-prefix pg1 -- -p 0x1 -P -m "[1:2].0"

pktgen (which version is 2.8.4) bind a VF of XL710 NIC, this adapter connect to a switch, and the port of switch works in trunk mode and permit vlan 265.

Then I execute following run time command.
vlan 0 on
vlanid 0 265
set 0 seqCnt 1
seq 0 0 58:6a:b1:48:bc:1a 00:20:14:10:20:11 194.136.86.100 194.136.86.1/24 0 0 ipv4 icmp 265 64

when I execute "start 0", I can not see any packets on switch, but if I execute "vlan 0 off", then "start 0", I can see packets arrived at switch port.

Thanks a lot!
