[dpdk-dev] Any benefit of using DPDK's makefiles instead of using

Anyone knows how to turn off TSO in DPDK+SR-IOV in KVM guest VM ? I want the packets sending out of the KVM host not to have TSO by the hardware. I imagine that I need to do the following: 1. turn off TSO in the guest before starting DPDK using ethtool -K ethX tso off After DPDK is started, th

[dpdk-dev] Is Flow Director supported on the x540 chipset?

Hi Fulvio, I have been checked few information about the datasheet of the X540 card. The X540 card is a derivative of the 82599. It's very similar to the 82599 card. The both cards use the same hardware registers for the flow director. Thus, the current code of the dpdk for the flow director shou
