Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: yux.jiang@intel.com
Target Milestone: ---
[Environment]

[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.
1, Build latest main dpdk24.03-rc1
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Denable_kmods=True -Dlibdir=lib --default-library=shared
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf /root/tmp/dpdk_share_lib /root/shared_lib_dpdk
DESTDIR=/root/tmp/dpdk_share_lib ninja -C x86_64-native-linuxapp-gcc -j 110
install
mv /root/tmp/dpdk_share_lib/usr/local/lib /root/shared_lib_dpdk
ll /root/shared_lib_dpdk
cat /root/.bashrc | grep LD_LIBRARY_PATH
sed -i 's#export LD_LIBRARY_PATH=.*#export
LD_LIBRARY_PATH=/root/shared_lib_dpdk#g' /root/.bashrc
2, Build LTS dpdk23.11.0
rm /root/dpdk
tar zxvf dpdk_abi.tar.gz -C ~
cd ~/dpdk/
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Denable_kmods=True -Dlibdir=lib --default-library=shared
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf x86_64-native-linuxapp-gcc/lib
rm -rf x86_64-native-linuxapp-gcc/drivers
3, Bind nic
rmmod vfio_pci
rmmod vfio_iommu_type1
rmmod vfio
modprobe vfio
modprobe vfio-pci
usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:18:00.0 0000:1a:00.0
4, Launch dpdk-test and run link_bonding_autotest
x86_64-native-linuxapp-gcc/app/dpdk-test -c 0xff -d /root/shared_lib_dpdk -a
0000:18:00.0 -a 0000:1a:00.0
RTE>>link_bonding_autotest
Show the output from the previous commands.

ethdev: add Tx queue used count query
Introduce a new API to retrieve the number of used descriptors
in a Tx queue. Applications can leverage this API in the fast path to
inspect the Tx queue occupancy and take appropriate actions based on the
available free descriptors.
A notable use case could be implementing Random Early Discard (RED)
in software based on Tx queue occupancy.
