NAME

ieef- Intel EtherExpress Flash32/82596 Ethernet device driver

SYNOPSIS

#include <sys/stropts.h>

#include <sys/ethernet.h>

#include <sys/dlpi.h>

#include <sys/gld.h>

DESCRIPTION

The ieef Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P), over Intel EtherExpress Flash32 Ethernet controllers, or the Unisys family of on-motherboard and add-on ethernet implementations using the Intel 82596 network controller.

Multiple controllers installed within the system are supported by the driver. The ieef driver provides basic support for the above mentioned hardware. Functions include hardware initialization, frame transmit and receive, multicast and "promiscuous" support, and error recovery and reporting.

The cloning, character-special device /dev/ieef is used to access all EtherExpress Flash32/82596 devices installed within the system.

ieef and DLPI

The ieef driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the ieef driver with the DLPI and STREAMS functionality required of a LAN driver. See gld(7D) for more details on the primatives supported by the driver.

The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ from the user are as follows:

The maximum SDU is 1500 (ETHERMTU).
The minimum SDU is 0. The driver will pad to the mandatory 60-octet minimum packet size.
The dlsap address length is 8.
The MAC type is DL_ETHER.
The sap length value is -2, meaning the physical address component is followed immediately by a 2-byte sap component within the DLSAP address.
