[dpdk-dev] flow director on X550

[Nishant Verma]

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: 0x800001cf
     - 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 0xffff -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 0000 dst
66.66.66.66 0000 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.
