Add references to ATAPI support; do a quick job from UTSL on scanners, and the changer thing. Also document that SCSI bus Ethernet interface that appears to be supported. Clean up some nroff stuff in the exiting pages.

.Nd Cabletron EA41x SCSI bus Ethernet interface driver
|
|
.Sh SYNOPSIS
|
|
.Cd "se* at scsibus? target ? lun ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports the
|
|
.Tn Cabletron
|
|
EA41x
|
|
.Tn SCSI
|
|
bus
|
|
.Tn Ethernet
|
|
interface.
|
|
.Pp
|
|
This driver is a bit unusual.
|
|
It must look like a network interface and it must also appear to be a
|
|
.Tn SCSI
|
|
device to the
|
|
.Tn SCSI
|
|
system.
|
|
.Pp
|
|
In addition, to facilitate
|
|
.Tn SCSI
|
|
commands issued by userland programs, there are
|
|
.Fn open ,
|
|
.Fn close ,
|
|
and
|
|
.Fn ioctl
|
|
entry points.
|
|
This allows a user program to, for example,
|
|
display the EA41x statistic and download new code into the adaptor \-
|
|
functions which can't be performed through the
|
|
.Xr ifconfig 8
|
|
interface.
|
|
Normal operation does not require any special userland program.

Acknowledgement: Thanks are due to Philip L. Budne <budd@cs.bu.edu>
|
|
who reverse engineered the the EA41x.
|
|
In developing this code, Phil's userland daemon "etherd",
|
|
was refered to extensively in lieu of accurate documentation for the device.
|
|
.Sh BUGS
|
|
The EA41x doesn't conform to the
|
|
.Tn SCSI
|
|
specification in much at all.
|
|
About the only standard command supported is
|
|
.Qq inquiry .
|
|
Most commands are 6 bytes long, but the recv data is only 1 byte.
|
|
Data must be received by periodically polling the device with the
|
|
recv command.
