driver supports the Cabletron EA41x SCSI bus
Ethernet interface.
This driver is a bit unusual. It must look like a network interface and it must also appear to be a SCSI device to the SCSI system.
In addition, to facilitate SCSI commands issued by userland
programs, there are open
(),
close
(), and 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
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 EA41x. In developing this code, Phil's userland daemon "etherd", was referred to extensively in lieu of accurate documentation for the device.
