elx - 3COM EtherLink III Ethernet device driver
The elx Ethernet driver is a multi-threaded, loadable,
clonable, STREAMS hardware driver supporting the connection-
less Data Link Provider Interface, dlpi(7P), over the fol-
lowing 3COM ETHERLINK III Ethernet controllers. For x86
based systems: 3C509, 3C509B, 3C579 and 3C59x controllers.
Multiple EtherLink III controllers installed within the sys-
tem are supported by the driver. The elx driver provides
basic support for the EtherLink III hardware. Functions
include chip initialization, frame transmit and receive,
multicast and "promiscuous" support, and error recovery and
The cloning, character-special device /dev/elx is used to
access all EtherLink III devices installed within the sys-
The elx driver is dependent on /kernel/misc/gld, a loadable
kernel module that provides the elx 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 primi-
tive in response to the DL_INFO_REQ from the user are as
o The maximum SDU is 1500 (ETHERMTU).
o The minimum SDU is 0. The driver will pad to the man-
datory 60-octet minimum packet size.
o The dlsap address length is 8.
o The MAC type is DL_ETHER.
o The sap length value is -2, meaning the physical
address component is followed immediately by a 2-byte
sap component within the DLSAP address.
o The broadcast address value is Ethernet/IEEE broadcast
