5-tuple support on dpdk

Hi,

I am trying to segregate data on basis of destination tcp/udp port and send them to different RX queues. From where different applications will read from their corresponding queues.

So I tried to implement 5 tuple filter but all the data is going to default RX queue 0 instead of setting destination to RX 1 or 2. I am using testpmd command for prototype purpose. Below is the command I am using.

5tuple_filter 0 add dst_ip 2.2.2.2 src_ip 3.3.3.3 dst_port 2049 src_port 32 protocol 0x06 mask 0x0 tcp_flags 0x0 priority 7 queue 2

and network card is

Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection with dpdk-2.1.0 version.

Though Ether type filter is working on the same card which redirects data to different RX queues. But my requirement is segregation of tcp/udp port basis not on IP or ethernet port basis.

Please provide your valuable suggestions.

Regards

-Deepak

thanks for responding Carlos. Yes..I have been referring to same document from starting. Above command that I posted , have been taken from same document. I am using dpdk-2.1.0. Somehow all the packets are going to RX queue 0 and not RX queue 1. I went through different threads already present, but I could not find the root cause of this behaviour.

Is there any setup related requirements for this filter. Ethernet filter is working but 5 tuple filter is not working. I have seen statistics of different RX queue's using stat_qmap . Which register value should I check for 5 tuple filter to see if the filter was properly set. I think rss is implemented in test-pmd application which might be causing it anyway I have tried to disable it also.

I am having hard times configuring this filter .please help
