Test Setup
Steps to reproduce
==================
1.Build dpdk
CC=gcc meson -Dlibdir=lib --default-library=static x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
meson configure -Dexamples=l3fwd-power x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
2.Start dpdk-l3fwd-power
usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:38:00.0 0000:38:00.1
/root/dpdk/x86_64-native-linuxapp-gcc/examples/dpdk-l3fwd-power -l 1-2 -n 1 --
-p 0x1 -P --config="(0,0,2)" -u

[--max-pkt-len PKTLEN]
-p PORTMASK: hexadecimal bitmask of ports to configure
-P: enable promiscuous mode
-u: set min/max frequency for uncore to minimum value
-U: set min/max frequency for uncore to maximum value
-i (frequency index): set min/max frequency for uncore to specified frequency
index
--config (port,queue,lcore): rx queues configuration
--eth-link-speed: force link speed
--cpu-resume-latency LATENCY: set CPU resume latency to control C-state
selection, 0 : just allow to enter C0-state
--high-perf-cores CORELIST: list of high performance cores
--perf-config: similar as config, cores specified as indices for bins
containing high or regular performance cores
--no-numa: optional, disable numa awareness
--max-pkt-len PKTLEN: maximum packet length in decimal (64-9600)
--parse-ptype: parse packet type by software
--legacy: use legacy interrupt-based scaling
--telemetry: enable telemetry mode, to update empty polls, full polls, and
core busyness to telemetry
--interrupt-only: enable interrupt-only mode
--pmd-mgmt MODE: enable PMD power management mode. Currently supported modes:
baseline, monitor, pause, scale
--max-empty-polls MAX_EMPTY_POLLS: number of empty polls to wait before
entering sleep state
--pause-duration DURATION: set the duration, in microseconds, of the pause
callback
--scale-freq-min FREQ_MIN: set minimum frequency for scaling mode for all
application lcores (FREQ_MIN must be in kHz, in increments of 100MHz)
--scale-freq-max FREQ_MAX: set maximum frequency for scaling mode for all
application lcores (FREQ_MAX must be in kHz, in increments of 100MHz)
EAL: Error - exiting with code: 1
Invalid L3FWD parameters
Expected Result:
Startup successful
