I dig into this a little bit, it looks like it will need the modules
extra package for the Ethernet interface driver.

$ lspci -nnv
00:00.0 Ethernet controller [0200]: Google, Inc. Compute Engine Virtual Ethernet [gVNIC] [1ae0:0042] (rev 01)

$ modinfo gve
filename:       /lib/modules/6.8.0-1015-gcp/kernel/drivers/net/ethernet/google/gve/gve.ko
...

For 5.15 we do have this driver available for generic kernel:
$ dpkg -S /lib/modules/5.15.0-125-generic/kernel/drivers/net/ethernet/google/gve/gve.ko
linux-modules-extra-5.15.0-125-generic: /lib/modules/5.15.0-125-generic/kernel/drivers/net/ethernet/google/gve/gve.ko

However the modules-extra package for 64k kernel is not installable (and
just suggested by kernel-testing--linux--full--generic-64k).

$ sudo apt install linux-modules-extra-5.15.0-125-generic-64k

Package linux-modules-extra-5.15.0-125-generic-64k is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'linux-modules-extra-5.15.0-125-generic-64k' has no
installation candidate

$ sudo apt install kernel-testing--linux--full--generic-64k
