===========
DPDK version: e5176f23ae8b31437c3e5eb875c81f95bf3a9942 version: 25.03-rc1
OS: Ubuntu24.04.1 LTS (Noble Numbat)/6.8.0-41-generic
Compiler: gcc version 13.2.0
Hardware platform: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz
NIC hardware: NNT(82599ES 10-Gigabit SFI/SFP+ Network Connection 10fb)
NIC firmware:
driver: ixgbe-5.22.25
FW: 0x000161bf
Test Setup
Steps to reproduce
==================
1. bind ports to dpdk
./usertools/dpdk-devbind.py -b vfio-pci 0000:b1:00.0 0000:b1:00.1
2. launch testpmd
x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-39 -n 4 -a 0000:b1:00.0 -a
0000:b1:00.1 -- -i
3. create bonding device
port stop all
create bonding device 4 1
add bonding member 0 2
add bonding member 1 2
4. set bonding lacp
set bonding lacp dedicated_queues 2 enable
port start all
show port info all
Results:
========
the link status of all ports is down and have some error info.
Please remove port 0 from bonding device.
Please remove port 1 from bonding device.

Done
Expected Result:
================
The status of all ports is normal.

net/bonding: fix dedicated queue setup
The bonding PMD hardcoded the value of dedicated hardware Rx/Tx
queue size as (128/512). This will cause the bonding port start
fail if some NIC requires more Rx/Tx descriptors than the hardcoded
number.
Therefore, use the minimum hardware queue size of the member port
to initialize dedicated hardware Rx/Tx queue. If obtaining the
minimum queue size failed, use the default queue size.
Fixes: 112891cd27e5 ("net/bonding: add dedicated HW queues for LACP
control")
