[dpdk-users] Problems running test-pipeline.

[Arto Sänkiaho]

Hello, i am new with DPDK and i am trying to run the test-pipeline program.

Here is the output when i run it:

./testpipeline -c 0x07 -- -p 0x01

Here is the nic bind info

$ dpdk_nic_bind -s

Changing port mask to 0x04 or any other value gives following error:

What i'm doing wrong here ?

There is probably some configuration step missing or misconfiguration but i
could not figure out what it is.

Thank you in advance.
