.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.
