[dpdk-dev] [PATCH] pcap: remove test for PCAP_CAN_SEND

The libpcap library has had the ability to send packets since 2004, theres really no need to test for it. Especially in the way dpdk is doing as, as according to the libpcap git tree pcap_sendpacket has never been a #define, and dpdk tests for its existance with an #ifdef. Its easier just to remo

[dpdk-dev] VM does not receive any packets from testpmd using SR-IOV VF PMD

Hi folks, I have two Intel Xeon servers connected back-to-back using Intel 82599 NICs (a sender to a receiver). I followed the steps in DPDK manual section 9.3 and use single VF direct pass-through to the VM and run testpmd on the VF at the receiver. At the sender side, I run Pktgen and program th

[dpdk-dev] testpmd only receive 127 packets, then becomes all RX-errors

After trial and error, I found it's because I only enable one port, so once the packet fills up all my rx descriptor, the rest of incoming packet becomes RX-errors. If I set the rxd to 2048, then the RX-packets will be 2047. ./testpmd -c 0xff -n2 -v -m 128M -- --burst=128 -i --rxq 2 --txq 2 --rxd

[dpdk-dev] Achieve maximum transmit rate using Intel DPDK

Hi all, Does anyone know on what are the optimal settings that should be provided, so as to get the maximum transmit rate for an NIC using Intel DPDK ?

[dpdk-dev] testpmd only receive 127 packets, then becomes all RX-errors

Hi folks, I'm using two servers connected back to back using 2 Intel 82599 10G NICs to test the dpdk. At the sender side, I use dpdk Pktgen to generate UDP packet. I program the destination mac statically to make sure no ARP is necessary. My first experiments using Pktgen on both sender and rece

[dpdk-dev] Questions on use of multiple NIC interfaces

Hi all, Could someone answer the following questions about the usage of multiple NIC interfaces with DPDK? 1. If my server has two identical Intel NICs, could I use both with DPDK and its applications? 2. If both the NIC cards could be used with DPDK, could I use them with separate instances
