[dpdk-dev] Intel 82599ES send packets failed on dpdk-17.05.1 after traffic testing

[zimeiw]

hi,
My test env is dell T430 server, NIC is intel 82599ES.
I integrate my app with dpdk-17.05.1 version. after do some tcp traffic testing, app can receive packets from the 82599 NIC, but 82599 NIC send packets failed.
But my app with dpdk-17.02 works well. 


If any change with ixgbe driver? or need some additional configuration for the NIC?



Thanks.
