is there any hope for this one?
tlp0 at pci2 dev 5 function 0: ADMtek AN985 Ethernet, pass 1.1
tlp0: broken MicroWire interface detected; setting SROM size to 1Kb
tlp0: interrupting at irq 10
tlp0: reset failed to complete
tlp0: Ethernet address ff:ff:ff:ff:ff:ff
The PCI ID matches
product ACCTON EN2242 0x1216 EN2242 10/100 Ethernet
There is a subsystem ID of SMC/0xc255.
The chip itself is labeled "SMC EN5251B".
Setting "tlp_srom_debug" shows that only "0xff"s are read from
However, there _is_ an EEPROM on the board (93LC46).
The board is a new SMC one with a 100TX and a fibre connector,
its name is "SMC 1255FTX-SC".
There is nothing which looks like an external MII PHY chip.
The Linux "tulip" driver recognizes it as:
ADMtek Comet rev 17
and gets the ethernet address right.
100TX seems to work; connecting a fibre hung the box.
A brief look at the Linux driver made me believe that the ethernet address
is read from io registers at offset 0xa4/0xa8, but I couldn't reproduce this
on NetBSD - perhaps an initialization matter, or a misunderstanding of the
