NAME
     xge - Neterion Xframe  10Gigabit  Ethernet  Network  Adapter
     driver

SYNOPSIS
     /dev/xge


DESCRIPTION
     The xge 10 Gigabit Ethernet   driver  is  a  multi-threaded,
     loadable, clonable, GLD-based STREAMS driver supporting  the
     Data Link Provider Interface, dlpi(7P), on S2IO  Xframe  10-
     Gigabit Ethernet Network Adapter.


     The xge driver functions includes controller initialization,
     frame  transmit  and receive, promiscuous and multicast sup-
     port, TCP and UDP checksum offload (IPv4  and  IPv6),  9622-
     byte jumbo frame, and error recovery and reporting.


     The xge driver and hardware support the 10GBase-SR/W,  LR/W,
     and ER/W 802.3 physical layer.

APLICATION PROGRAMING INTERFACE
     The cloning,  character-special device /dev/xge is  used  to
     access all Xframe devices installed within the system.


     The xge driver is managed  by  the  dladm(1M)  command  line
     utility,  which  allows  VLANs  to  be defined on top of xge
     instances and  for  xge  instances  to  be  aggregated.  See
     dladm(1M) for more details.


     The values returned by the driver in the DLINFOACK  primi-
     tive in response to the DLINFOREQ are as follows:

         o    Maximum SDU is 9600.

         o    Minimum SDU is 0.

         o    DSLAP address length is 8 bytes.

         o    MAC type is DLETHER.

         o    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/IE  broadcast
              address (F:F:F:F:F:F).

CONFIGURATION
     By default, the xge driver works without  any  configuration
     file.


     You can check the running-time status of a device   instance
     using  ndd(1M).  Currently, the driver provides an interface
     to print all hardware statistics.


     For example, to print statistics of device xge0:

            #ndd /dev/xge0 stats
            tmacdataoctets 772
            tmacfrms 15
            tmacdropfrms 0
            tmacbcstfrms 6
            tmacmcstfrms 6

            ...

            rmacvldfrms 13
            rmacfcserrfrms 0
            rmacdropfrms 0
            rmacvldbcstfrms 7
            rmacvldmcstfrms 11
            rmacoutrnglenerrfrms 0
            rmacinrnglenerrfrms 0
            rmaclongfrms 0

            ...

            trafficintrcnt 28
