I think you simply need to explicitly list the device in the device tree, and a
SMBIOS type 41 entry will be generated automatically.
The NIC is defined in the device tree like this:
https://github.com/coreboot/coreboot/blob/master/src/mainboard/asrock/b75m-itx/devicetree.cb#L57-L59
I don't see anything wildly different to other boards I have, which do
show their onboard NIC as eno0 instead of enpXsX.
Seems with CONFIG_SMBIOS_TYPE41_PROVIDED_BY_DEVTREE you can even control
which NIC gets what index if you have more than one.
But this does not seem to be set for any board by default. So I don't
think it's a requirement for this to work; more like a hard override.
As stated, on my X230, P8Z77-V and GA-G41M-ES2L, the onboard NIC is
called eno0 (as it should be). On my B75M-ITX it's called enp3s0, and on
my B75 Pro3-M it's called enp4s0.
So coreboot doesn't seem to pass the "this device is onboard and its
index is 0" message properly.
I can see `if (!dev->on_mainboard)` in smbios.c, but I can't find where
that flag is set.
