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(7P), over Chelsio NIC controllers. Multiple (and  mixed) NIC controllers installed within  the	 system  are  sup-
       ported  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(7D) 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).
