Subject: SR-IOV dpdk testpmd bonding does not work
To: test-report at dpdk.org


Hi

I have a problem with dpdk testpmd bonding,I think may be a bug

Test env

under test machine and traffic sender machine connect directly

each machine have two ports

[xxx]# dpdk-devbind -s

at the same time ,use tcpdump capture the packets with another port p7p2
,find that the response packets at this port , so strange ...
because the under test machine vm's testpmd bond mode is active backup mode
.I do not think this port should receive packets .but it is true.

follow the stat result , I find that port 0 only receive packets and port 1
only send packets. but current the bond mode is below (active-backup mode )

testpmd> show bonding config 2
    Bonding mode: 1
    Slaves (2): [0 1]
    Active Slaves (2): [0 1]
    Primary: [0]

I do not know why the result is this .could some one can help me . Thanks.
