(In reply to Patrick M. Hausen from comment #24)
Thanks you for the testing. I think I found what is causing the crash.
ue->ifp is NULL

I made a new patch. Please undo the previous two and apply this one.
git restore sys/dev/usb/net/if_smsc.c
git restore sys/net/if_ethersubr.c
<apply this patch>
<build kernel>
<boot>

Please make a picture again about what happens.

If this works I have a bonus for you. 🤩🤩🤩
With the patch applied change line 1657 in if_smsc.c from "#if 0" to "#if 1".
<build kernel>
<boot>

This should give you the MAC address supplied by Raspberry Pi.
