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>
AVAILABILITY x86
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 func-
tionality required of aLAN driver. See gld(7D) for more details about primitives sup-
ported 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.
MultipleSMC 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 theDL_INFO_ACK primitive in response to the
DL_INFO_REQ from the user are:
The maximum SDU is 1500 (ETHERMTU).
The minimumSDU 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 fol-
lowed immediately by a 2-byteSAP 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 theSMC
Elite32 Ultra (8232) Device Configuration page in the x86 Device Configuration Guide for
information regarding hardware configuration.
