Hi everybody
I haven't been able (for several days) to attach a DPDK interface to the
ovs :(:(
Device 0000:05:00.0 is in userspace with driver vfio
root@s131002:~# dpdk-devbind -s
Network devices using DPDK-compatible driver
============================================
0000:05:00.0 '82576 Gigabit Network Connection 10c9' drv=vfio-pci
unused=uio_pci_generic
But when I try to attach it to a dpdk bridge I got this error
2018-05-26T21:34:24Z|00630|dpdk|WARN|EAL: Requested device 0000:05:00.0

Could any of you, with more expertise on the topic, please, provide me some
pointers?
I have tried all kind of combinations. and I am probably still thinking
within the box.....
I would really appreciate your kind guidance.
