X710 Flow director issues on Linux

song-lee Jul 31, 2017 2:18 AM

Hello all,

I am not able to setup Flow Director to filter flow type ipv4. It did not seems to have this issue when flow type is specified as tcp.

Its on Linux(4.9.27), freshly download driver off kernel. Below there is output of the driver version, firmware and the ntuple filter I want to apply on.

No error shown anywhere.

Thank you!

Hi Song-Lee,

Thank you for posting at Wired Communities. Just to double check if you have check on the DPDK support site for more information:

Hello Sharon,

Thank you for your swift reply, but I do not see how DPDK support will help me, since I am not using their driver.

Regards

Hi Song-Lee,

Thank you for the clarification. what is the exact X710 network adapter model you have? Are you saying when you run the test, the packet did not go into the specific queue as what flow director configured?

Thanks,
sharon

Hi Sharon,

The exact mode is X710-DA2. The filter I want to apply should actually drop the traffic, but it does not. The queue redirection is working.

#ethtool -U i40e1 flow-type ip4 action -1 loc 1

Thank you!

Hi Sharon,

I do no see any difference - the same problem appears with this version of the driver.

Thanks!

Please help confirm if your kernel version is 2.6.30 or higher as required, you may refer to note of Intel Flow director stated at https://downloadmirror.intel.com/24411/eng/readme.txt

Hello Sharon,

I would really like to make some progress on this issue.

We used this feature quite a bit previously on our ixgbe setup and were quite surprised,
that it's not working on i40e, as expected.

I think I have supplied all the information to track the problem - the kernel version, the driver version and
the firmware, along all the interface settings and the actual filter we are applying.
If I had missed something, I'll gladly supply this information also.

Thanks for your effort!

I appreciate it!
