Hi,
I'm trying to run l3fwd-power application for 2 Port with queue. Always
only queue 1 of port 0 and port 1 are utilized.
CPU C-state, hpet are enabled, ports are binded to igb_uio.
Tried with NIC's x772 (10 GbE) and XXV710(25 GbE), Observed same behavior.
I am observing the below output:
*/root/comms/dpdk/examples/l3fwd-power/build/l3fwd-power -l 2,3,4,5 -n 6

I would appreciate it if some expert can shade a light on this.

Igb_uio does not support per-queue interrupts. That needs MSI-X which is
only supported by VFIO-pci.

Hi Stephen,
Thanks for your email.
Tried binding the NIC's to vfio-pci. Observed still queue 0 of Port 0, Port
1 has been utilized. No interrupts for queue 1.
