[dpdk-users] L3fwd-power queue utilization issue.

[Soumen Chandra Laha <soumen.laha32@gmail.com>]

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.
