  Missing all modules for usb nics in initrd which makes PXE boot
  impossible

Bug description:
  initrd taken from the live iso for PXE boot does not contain USB NIC
  drivers which makes PXE installation/netboot impossible via usb.

  This is the case on 20.04 server iso (both hwe and normal
  kernel/initrd) and desktop iso.

  "kernel/drivers/net/usb" is empty and needs to be included in the
  initramfs build.

  As most modern thin laptops lack physical rj45 ethernet this is a big
  issue.
