A variant of ep(4) for PCMCIA works just fine for amiga:

---
NetBSD 9.99.85 (A1200_WSCONS) #14: Wed Jun 16 07:44:49 JST 2021
        rin@latipes:/sys/arch/amiga/compile/A1200_WSCONS
...
pcmcia0 at pccard0
ep0 at pcmcia0 function 0: <3Com, Megahertz 589E, TP/BNC LAN PC Card, 005>
ep0: address 00:50:04:cc:ee:7e, 8KB byte-wide FIFO, 5:3 Rx:Tx split
ep0: 10baseT, 10base5, 10base2 (default 10baseT)
---

This model does not have MII, and it seems that differences b/w
netbsd-8 and -9 are mostly in MII part.

Saitoh-san, do you have any idea?

Thanks,
