I have a Windows set-up on which I have one Intel XXV710 (2 x 25G port) and one
Intel E810 (2 x 100G port).

When using DPDK v23.11.2, if I bind the 4 NIC to netuio, when running
dpdk-testpmp, I have the following :

Logs show :

------------------------------------------------------------

I tried the following : 
- Only one i40e NIC bound to netuio : OK
- Only one ice NIC bound to netuio : OK
- Two i40e NIC bound to netuio : OK
- Two ice NIC bound to netuio : Second NIC can not be used
- one ice NIC and two i40e NIC bound to netuio : Second i40e NIC can not be
used
- two ice NIC and two e40e NIC bound to netuio (as above) : second i40e and
second ice NIC can not be used

------------------------------------------------------------

When using v24.07, the problem is not present :

No message regarding "NIC can not be used is present".

Any plan on fixing this behavior in 23.11?
