[dpdk-users] DPDK ip-pipeline error when using virtual function interface

[Murad Kablan]

Hi, I would like to try ip-pipline sample application and I'm getting the
below error. The virtual functions work fine with l2fwd application though.

I find this thread is close to my problem, however that solution didn't
workout for me.

My server is Ubuntu 14.04 with kernel 3.19.

dpdk_nic_bind.py --status

This is the error when I run
./build/ip_pipeline -p 0x01
