Hi, I have DPDK 1.5 configured on my machine, I have also configured the rump kernel tcpip stack. Now, to check whether the setup works, I started *TCP Server application*on another machine and connected the LAN cable to the port which is controlled by DPDK. And I am running *TCP client applicatio

Hi Thomas, Thanks for reply. The kernel has older version of PF than the one released on sf.net. So I'm checking the sf.net release. If the change is limited in DPDK then it is controllable. But now it affects Intel's PF driver, I don't even know how to push the feature to Intel. The driver on sf

Hi, I am doing experiments with SR-IOV + passthrough on 82599. My expectation is to have VT on and DCB off, under which configuration, the total 128 TX queues will be split into 32 pools, each has 4 queues. With latest driver ixgbe-3.18.7, PF can be set with 16 pools, each has 4 queues with these
