NAME

el - 3COM 3C503 Ethernet device driver

SYNOPSIS

#include <sys/stropts.h>

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

DESCRIPTION

The el Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P), over 3COM 3C503 EtherLink II and EtherLink II/16 Ethernet controllers. The el driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the el 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.

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

The cloning, character-special device /dev/el is used to access all EtherLink II devices 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 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).
