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 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 func‐
       tionality 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:

	 ·  Default Maximum SDU is 1500 (ETHERMTU).

	 ·  dlsap address length is 8.

	 ·  MAC type is DL_ETHER.

	 ·  The sap length value is  -2, meaning  the  physical address compo‐
	    nent  is followed immediately by a 2-byte sap component within the
	    DLSAP address.

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