Good afternoon,

When running latest DPDK, commit fd233ad17e5ffa42d50f1625165a7fce3f1cbc5f, I have a found an issue with running the qos_sched app with the configuration file present at the end of this email.

DPDK was built with the following options. meson --reconfigure --buildtype=debugoptimized -Dexamples=qos_sched -Db_sanitize=address build

The process is run as follows. Of note, with the default config files, the process starts and is executed as expected.
.build/examples/dpdk-qos_sched -l 29-32 -n 4 -a 86:01.0 -a 86:01.1 -a 86:01.2 -- --pfc "0,0,30,31,32"   --cfg /home/ubuntu/dpdk/examples/qos_sched/65kpipe_25gb_pipe_alloc_buggy.cfg --mnc 29  --bsz "128,512,511,511"  --rsz "4096,32768,4096" -i

The error seen is the following.

EAL: Detected CPU lcores: 112
EAL: Detected NUMA nodes: 2
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'VA'
EAL: VFIO support initialized
EAL: Using IOMMU type 1 (Type 1)
Interactive-mode selected
APP: Initializing port 11... ETHDEV: Invalid port_id=11
EAL: Error - exiting with code: 1
Error during getting device (port 11) info: No such device

The following is the ASAN output. I am unfortunately unable to pursue this any further. Could anyone please give some assistance?
