Hello maintainers of hw-detect,
The new version of ethdetect.sh does not detect the network interfaces when
booting from BIOS.
This can be seen on openQA [1] where the installer fails to find the network
interfaces for the BIOS scenarios. The UEFI scenarios still work.
From the d-i syslog (broken, BIOS) [2]:
Jul 29 21:33:12 main-menu[430]: INFO: Menu item 'ethdetect' selected
Jul 29 21:33:17 net/hw-detect.hotplug: Detected hotpluggable network interface

From the d-i syslog (last working, BIOS) [3]:

After 1.176 entered unstable, all BIOS installer tests started to fail. There
are no version differences in the other udebs, so that's why I report against
hw-detect.
I think it might be caused by the 'Change hw-detect/firmware-lookup type to
string' change, since that influences whether the network interface is taken
down and up again.
With kind regards,
Roland Clobus
