[dpdk-dev] Changes to 5tuple IPv4 filters in dpdk v2.0

Hi DPDK community, I've been using DPDK v1.7 and v1.8 for the past year. On updating to v2.0.0, I see that *rte_5tuple_filter* has been deprecated as well as the associated install/remove call,* rte_eth_dev_add_5tuple_filter()* I now see that rte_eth_ntuple_filter has been added in place. 1) Is

[dpdk-dev] Filtration Statistics for VLAN filters(ixgbe)

Hello, I am trying to implement VLAN filters in DPDK on 82599 NIC(Niantic) I've been using *rte_eth_dev_vlan_filter(port, vlanID, 1)* which seems to be working however I would like to see some actual packet filtration statistics. In the case of 5tuple IPv4 filters where I was redirecting to que

[dpdk-dev] RSS Reta redirection not working on 82599 NIC(Niantic)

Hello, Following from a previous thread, I took up Bruce Richardson's advice to modify the RSS redirection table(RETA) to exclude entries pointing to a specific queue: For e.g, this is the RETA table before any modifications are done: *Default *Reta table: 0 1 2 0 1 2 0 1 2 0 1 2 0 1 2 0 1 2 0 1

orwarding to that specific queue. Is there a way to EXCLUSIVELY bind a 5tuple filter to an RSS queue so that only matched traffic is forwarded there? --Kam On Wed, Jan 14, 2015 at 5:27 AM, Bruce Richardson < bruce.richardson at intel.com> wrote: > On Tue, Jan 13, 2015 at 11:21:08PM -0

[dpdk-dev] Does I210 NIC support Flow director filters?

Hello, I've been using DPDK fdir filter APIs for 82599 NIC(Niantic) and they work very well. Was wondering if I these could also be used for I210, 1Gbps NICs? The other option is to use 5tuple filters(rte_eth_dev_add_5tuple_filter

[dpdk-dev] Symmetric RSS Hashing in DPDK

Hello, My DPDK application requires bidirectional TCP flows to have the same RSS hash however default RSS hashing is *asymmetric*. There are posts such as: http://dpdk.info/ml/archives/dev/2014-February/001460.html which point to a symmetric RSS key(0x6d5a). I have tried using it but it is still

Hello, I have ~15Gbps of traffic flowing through two 10GE ports and been profiling the rte mempool(or rather the pktmbuf mempool) memory consumption: I have per lcore caching disabled(cache_size is 0) I have noticed that: - Mempool FREE cnt(as given byt rte_mempool_free_count()) increases - Memp

Hello, So i've borrowed some code from the DPDK Load balancer sample application, specifically the load balancing position(byte 29th) to determine which worker lcore to forward the packet to. The idea is that flow affinity should be maintained and all packets from the same flow would have the sam

Greetings, I am still a DPDK newbie so not really sure how to go about doing this... I have a DPI daemon running in userspace which uses libpcap for packet RX that I would like to replace with DPDK ethernet PMD. However it is not feasible to convert the entire application to run within the DPDK f
