Hello,
I have a ConnectX-4 dual-100Gbps NIC that works with DPDK versions
24.03 and 24.07 but not with 24.11 or 25.03.
0000:04:00.0 'MT27700 Family [ConnectX-4] 1013' numa_node=0
if=enp4s0f0np0 drv=mlx5_core unused=vfio-pci
0000:04:00.1 'MT27700 Family [ConnectX-4] 1013' numa_node=0
if=enp4s0f1np1 drv=mlx5_core unused=vfio-pci
Setting the log levels to debug, the newer versions are unable to
configure more than one (1) description on any queue:
ETHDEV: Invalid value for nb_tx_desc(=1024), should be: <= 1, >= 0,
and a product of 1
Whereas using the older version, I am able to set a larger number of
descriptors. Tried 512, 1024, 2048 and 4096.
