[dpdk-dev] [PATCH] pcap: Fixed bug in eth_pcap_rx function

Normally, bufs[i] stores the mbuf pointer, the index of buf[i] is the loop count i, but if header.len > buf_size, DPDK will free the mbuf, but the loop count i still increases, so some of the items in bufs[] might be NULL ponter, causing a potential DPDK core. Using num_rx as the index for bufs[] s

[dpdk-dev] [Dpdk-ovs] Questions about the OpenStack Neutron with Intel Architecture document

Thank you for the reply. I installed DPDK 1.7.0 on RedHat 6.5 with Kernel 3.7.10 and it seems compiled successfully. When execute the HelloWorld example, however, there was a panic error as below: 1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size PANIC in rte_e

[dpdk-dev] [Dpdk-ovs] Questions about the OpenStack Neutron with Intel Architecture document

The command shows "nodev on /mnt/huge type hugetlbfs (rw)", so I think it has been mounted correctly. By the way, I could execute HelloWorld example file by setting all the things through ./tools/setup.sh I'm still not sure which part was not set correctly though. Thanks anyway. Best regards B

[dpdk-dev] Question on using SR-IOV with dpdk apps

I had this when the PF was down, bringing it back with "ifup" fixed it. Assuming you've already checked it's not the issue described in the FAQ :) With a RHEL 6.5 host the ixgbe driver prints the VF MAC addresses in /var/log/syslog when the VFs are enabled -Original Message- From: dev

[dpdk-dev] Question on using SR-IOV with dpdk apps

Since some version of ixgbe driver, it will not generate mac address for the VFs. You could use ip link set to set mac address for the VFs. > -Original Message- > From: dev [mailto:dev-bounces at dpdk.org] On Behalf Of Patrick McGleenon > Sent: Tuesday, August 05, 2014 10:39 PM > To: Anj

[dpdk-dev] Recommended LNS-compatible host interface?

Hi, DPDK supports a number of different interface types. Given this, at this time what is the favoured (virtual) interface type for host-only applications where Linux network stack compatibility is required? Previously we used KNI (we found this to be "unreliable" when not bound to a real ethde

[dpdk-dev] [PATCH 0/3] vhost example based on user space vhost library.

This vhost example implements a simple vswitch using DPDK user space vhost library(lib/librte_vhost) and VMDQ to demonstrate vhost's performance. - Each virtio device is bound to a VMDQ pool and each pool is assigned the mac/vlan of the virtio device. - Packets arriving at a pool after l2 classif
