CHXGE(4D) Devices CHXGE(4D)

NAME

chxge - Chelsio Ethernet network interface controllers

SYNOPSIS

/dev/chxge

DESCRIPTION

The chxge Ethernet driver is a multi-threaded, loadable, clonable,
STREAMS hardware driver supporting the connectionless Data Link
Provider Interface, dlpi(4P), over Chelsio NIC controllers. Multiple
(and mixed) NIC controllers installed within the system are
supported by the driver. The chxge driver provides basic support
for the NIC hardware. Functions include chip initialization, frame
transmit and receive, and error recovery and reporting.

APPLICATION PROGRAMMING INTERFACE

The cloning, character-special device /dev/chxge is used to access
NIC devices installed within the system.

CHXGE AND DLPI

The chxge driver is dependent on /kernel/misc/gld, a loadable kernel
module that provides the chxge driver with the DLPI and STREAMS
functionality required of a LAN driver. See gld(4D) for more details
on the primitives supported by the driver.

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

o Default Maximum SDU is 1500 (ETHERMTU).

o dlsap address length is 8.

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