NAME

smceu- SMC Elite32 Ultra (8232) Ethernet device driver

SYNOPSIS

#include <sys/stropts.h>

#include <sys/stream.h>

#include <sys/dlpi.h>

#include <sys/ethernet.h>

DESCRIPTION

The smceu Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface over an SMC Elite32 Ultra (8232) EISA-bus adapter. The smceu driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the smceu driver with the DLPI and STREAMS functionality required of a LAN driver. See gld(7D) for more details about primitives supported by the smceu driver.

The smceu driver provides basic support for the SMC Elite32 Ultra hardware. Functions include chip initialization, frame transmission and reception, multicast and promiscuous support, and error recovery and reporting.

Multiple SMC Elite32 Ultra controllers installed within the system are supported by the driver.

APPLICATION PROGRAMMING INTERFACE

The cloning character-special device /dev/smceu is used to access all SMC Elite32 Ultra controllers installed within the system.

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

The maximum SDU is 1500 ( ETHERMTU).
The minimum SDU is 0. Note that the smceu driver will pad to the mandatory 60-octet minimum packet size.
The dlsap address length is ETHERADDRL + 2.
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.
The broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).

CONFIGURATION

The driver is shipped configured to support any legal device configuration. See the SMC Elite32 Ultra (8232) Device Configuration page in the for information regarding hardware configuration.
