Thanks , I forget do "set portlist " cmd.

But there is another problem is

1. enable testpmd bond active-backup mode , do send packet test , packet
backtrack ,from some port out and then this port back.
2. down the active physical link , then testpmd show receive LSC event
,show port info all , find one port down .
3. send packet to the backup port that used by testpmd bond from another
side ,It does not work.

Thanks.
