Compulab's Fitlet3: Intel's Elkhart Atom X6425E with MARVELL PHY 88E1512 Ethernet

[Wolfgang Oelerich]

Hello,

recently, I „inherited“ one of Compulab‘s Fitlet3. I received it with 
Linux Mint installed and found all 4 available Ethernet ports working: 
2 of its extensional FACET card and 2 of Intel‘s Elkhart Lake Atom X6425E 
with MARVELL-type PHY „88E1512" at Atom's PCIe bus (see link below). 

Now, I tried a clean install of OpenBSD 7.3/AMD64 which smoothly worked 
out but only the FACET card Ethernet ports have been recognized properly. 
While assuming BIOS is ok since Linux Mint worked I am wondering how far 
the hardware combination of X6425E/MARVELL PHY 88E1512 is already set to 
be working or if there is some driver or other Kernel level code not available 
yet.

After clean OpenBSD 7.3/AMD64 install I did afterboot, syspatch and 
sysmerge. 

Also, from Compulab‘s / FitPC‘s R folks (Andrey Mazlin) I was 
redirected to OpenBSD groups because they were not able to help. Here is, 
what they replied to my support request: "The best solution is to rise a 
question at OpenBSD kernel support community. We did try to ask them and 
what we've got: "I was able to created an OpenBSD custom kernel with this 
NIC enabled, but the device is still a pci-device not a network 
interface."" [end of citation].

At first, I have a short question: should first booting of 
OpenBSD 7.3/AMD64 have recognized mentioned hardware properly? 
If yes, I will follow-up at „sendbug“ with enclosed system info.

Would appreciate any answer. 
Kind regards 
Wolfgang
