[U-Boot] sandbox: Net: No ethernet found.

Hello Simon,

when I run sandbox_defconfig I always get Net: No ethernet found.

The dm command shows no driver attached to uclass 21: eth. Why are the sandbox and sandbox-raw drivers not loaded?

device_bind_common is not called for these drivers.

arch/sandbox/dts/sandbox.dts makes assumptions about the naming of interfaces:

host-raw-interface = "eth0"

With systemd eth0 tends not to exist. The interfaces on my Debian Buster system the interfaces are called lo, enp0s25, and wlp12s0.

Shouldn't we use if_nameindex() to enumerate the interfaces?

Best regards

Heinrich
