.SH NAME
chxge \- Chelsio Ethernet network interface controllers
.SH SYNOPSIS
.LP
.nf
/dev/chxge
.fi
.SH DESCRIPTION
.sp
.LP
The \fBchxge\fR Ethernet driver is a multi-threaded, loadable, clonable,
STREAMS hardware driver supporting the connectionless Data Link Provider
Interface, \fBdlpi\fR(4P), over Chelsio NIC controllers. Multiple (and mixed)
NIC controllers installed within the system are supported by the driver. The
\fBchxge\fR driver provides basic support for the NIC hardware. Functions
include chip initialization, frame transmit and receive, and error recovery and
reporting.
.SH APPLICATION PROGRAMMING INTERFACE
.sp
.LP
The cloning, character-special device \fB/dev/chxge\fR is used to access NIC
devices installed within the system.
.SH CHXGE AND DLPI
.sp
.LP
The \fBchxge\fR driver is dependent on \fB/kernel/misc/gld\fR, a loadable
kernel module that provides the \fBchxge\fR driver with the DLPI and STREAMS
functionality required of a LAN driver. See \fBgld\fR(4D) for more details on
the primitives supported by the driver.
.sp
.LP
The values returned by the driver in the DL_INFO_ACK primitive in response to
the DL_INFO_REQ are:
.RS +4
.TP
.ie t \(bu
.el o
Default Maximum SDU is 1500 (ETHERMTU).
.RE
.RS +4
.TP
.ie t \(bu
.el o
dlsap address length is 8.
.RE
.RS +4
.TP
.ie t \(bu
.el o
MAC type is DL_ETHER.
.RE
.RS +4
.TP
.ie t \(bu
.el 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.
.RE
.RS +4
.TP
.ie t \(bu
.el o
Broadcast address value is Ethernet/IEEE broadcast address
(FF:FF:FF:FF:FF:FF).
