Won't help, as the kernel in question is specifically made for the 
Indigo R3K (IP12).

Same here.

I think so, see e.g. my post from October 2017 ([1]) although with a 
much older NetBSD kernel:

```

```

Last three bytes of the MAC address are bogus/anonymized.

I think at least the Indigo R4K can use the same GIO cards than an Indy, 
or let's say the Indy - as it came out later - can use the same cards 
than an Indigo R4K. Not sure about an Indigo R3K though.
