NAME

elink - 3COM 3C507 Ethernet device driver

SYNOPSIS

#include <sys/stropts.h>

#include <sys/ethernet.h>
#include <sys/dlpi.h>
#include <sys/gld.h>

DESCRIPTION

The elink Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P), over 3COM 3C507 EtherLink 16 Ethernet controllers. Multiple EtherLink 16 controllers installed within the system are supported by the driver. The elink driver provides basic support for the EtherLink 16 hardware. Functions include chip initialization, frame transmit and receive, multicast and "promiscuous" support, and error recovery and reporting.

APPLICATION PROGRAMMING

The cloning, character-special device /dev/elink is used to access all EtherLink 16 devices installed within the system.

INTERFACE

elink and DLPI

The elink driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the elink 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.

The broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
