Subject: Issues with basicfwd

I'm having trouble running the basicfwd example and would appreciate
any help.
I'm running Linux Mint 21.1 inside VirtualBox, and I've created two
NICs:
verghis@verghis-VirtualBox:~/dpdk-stable-22.11.1/build$
../usertools/dpdk-devbind.py --status
Network devices using DPDK-compatible driver
============================================
0000:00:03.0 '79c970 [PCnet32 LANCE] 2000' drv=vfio-pci unused=pcnet32
Network devices using kernel driver
===================================
0000:00:08.0 '82540EM Gigabit Ethernet Controller 100e' if=enp0s8 drv=e1000
unused=vfio-pci *Active*
The first is bound to vfio-pci, to be used by basicfwd, and the second
uses the normal e1000 driver.
But when I run the code, it doesn't seem to see the VFIO driver at all;
further, it seems to think that 00:08.0
is using a non-kernel driver - why?
Here's the debug output; it should pick up the single VFIO port. I
don't care about the 'even number of ports', that's
easy to fix.
My apologies if I'm overlooking something simple.
