bookworm versus noble - i40e netdevice name discrepancy

[Robert Moulton]

Thanks for the troubleshooting guidance. I had forgotten about the
createvt flag.

'udevadm info' output during installation (see below) didn't include
any 'eno1np0' references. Same deal with 'DEBIAN/30-interfaces' script
debug output.
On the newly-built ubuntu system, '/sys/class/net/eno1' doesn't exist.
'/sys/class/net/eno1np0' does exist, with no 'eno1' references in
udevadmin output.
