Hi,
We have a driver for this device in sys/dev/scsipi/if_se.c. It was
pretty popular with the pc532 crowd back in the day because SCSI was
the only expansion bus the pc532 had.
There are changes coming to the network stack and it's unlikely that
(a) anyone has such a device to test it, and (b) that the driver even
works currently because it's been so long since probably anyone ran
this code.
I propose we remove this driver.
If it's not too much work, it might be worth keeping because some newer
hardware will emulate it:

If this is the same chip as is in the DaynaPort SCSI-Link-T, I can offer
to test the driver.
