The
se 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.
