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 connection-
     less 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  load-
     able  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  primi-
     tive 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   broad-
              cast address (FF:FF:FF:FF:FF:FF).
