[dpdk-dev] flow director on X550
Hi Nishant, From: Nishant Verma [mailto:vnis...@gmail.com] Sent: Thursday, May 26, 2016 11:40 AM To: Lu, Wenzhuo Cc: dev at dpdk.org Subject: Re: [dpdk-dev] flow director on X550 Hi Wenzhuo, Thanks for the reply. ?As par datasheet, if flow director filter matches then RSS won't impact as RSS is the last filter to be applied on received packet. But just to confirm, i tried and still issue persist. Any other thing that you think i can try, please let me know. [Wenzhuo] After checking the code, according to our implementation you cannot mask all the L4 ports if you want to direct the L4 packets. With all the ports masked, flow director only handles the raw IP packets. It means UDP/TCP/SCTP packets will not be handled. There?s a workaround. You can change the dest port mask to 0x01 (or src port if you like). And add 2 filters, one for dest IP 66.66.66.66 + dest port 0, the other for dest IP 66.66.66.66 + dest port 1. Thanks.

Hi Wenzhuo, Thanks for the reply. ?As par datasheet, if flow director filter matches then RSS won't impact as RSS is the last filter to be applied on received packet. But just to confirm, i tried and still issue persist. Any other thing that you think i can try, please let me know. Thanks.

Hi All, My system configuration is ==>#. SuperMicro 1U - BIOS: 1.0a - Processor: Intel(R) Xeon(R) CPU D-1540 @ 2.00GHz - Onboard NIC: Intel(R) X552/X557-AT (2x10G) - Firmware-version: 0x81cf - Device ID (PF/VF): 8086:15ad /8086:15a8 - kernel driver version: 4.2.5 (ixgbe) I am working on DPDK 16.04 & pktgen 3.0.0 version. My intention is to test flow director based on just destination IP. It means, i will use test-pmd and configure flow director and fdir mask, from pktgen i will send packet and check if packets are going to right queue or not. Here is the procedure, that i follow. 1. I run testpmd * ./testpmd -c 0x -n 4 -- -i --portmask=0x3 --nb-cores=5 --disable-link-check --rxq=5 --txq=5 --pkt-filter-mode=perfect* 2. executed command "*port stop all*" 3. After that added fdir mask *flow_director_mask 0 mode IP vlan 0 src_mask 0.0.0.0 0:0:0:0:0:0:0:0 0x00 dst_mask 255.255.255.255 0:0:0:0:0:0:0:0 0x00* 4. Again executed command "*port start all*" 5. Now i added flow director filter. *flow_director_filter 0 mode IP add flow ipv4-udp src 0.0.0.0 dst 66.66.66.66 tos 0x00 ttl 0x00 vlan 0 flexbytes (0x00,0x00) fwd pf queue 4 fd_id 4* 6. after that "*start*" --- 7. On Pktgen side i just change destination Address to *66.66.66.66*, protocol to *UDP* and issue command start 0. --- Result 8. But instead of packet to queue 4, packets are going to queue 0.
