NAME
     myri10ge - Myricom Myri10GE 10Gb PCI Express NIC Driver

SYNOPSIS
     /dev/myri10ge*


DESCRIPTION
     The myri10ge Gigabit Ethernet driver  is  a  multi-threaded,
     loadable,  clonable,  GLD-based STREAMS driver that supports
     the Data  Link  Provider  Interface,  dlpi(7P),  on  Myricom
     Myri10GE 10-Gigabit Ethernet controllers.


     The myri10ge driver functions include controller initializa-
     tion,  frame transmit and receive, promiscuous and multicast
     support, multiple transmit and receive queues,  support  for
     TCP  Large  Send  Offload,  support  for  TCP  Large Receive
     Offload, and error recovery and reporting.

  Application Programming Interface
     The cloning character-special device, /dev/myri10ge, is used
     to access all Myricom Myri10GE 10 -Gigabit Ethernet dev ices
     installed within the system.


     The myri10ge driver is managed by the dladm(1M) command line
     utility. dladm allows VLANs to be defined on top of myri10ge
     instances and for myri10ge instances to be  aggregated.  See
     dladm(1M) for more details.


     You must send an explicit DL_ATTACH_REQ message to associate
     the opened stream with a particular device (PPA). The PPA ID
     is interpreted as an unsigned integer data  type  and  indi-
     cates  the  corresponding device instance (unit) number. The
     driver returns an error  (DL_ERROR_ACK)  if  the  PPA  field
     value  does not correspond to a valid device instance number
     for the system. The device is initialized  on  first  attach
     and de-initialized (stopped) at last detach.


     The values returned by the driver in the DL_INFO_ACK  primi-
     tive in response to your DL_INFO_REQ are:

         o    Maximum SDU is 9000.

         o    Minimum SDU is 0.

         o    DLSAP address length is 8.

         o    MAC type is DL_ETHER.

         o    SAP (Service Access  Point)  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 the Ethernet/IEEE broad-
              cast address (FF:FF:FF:FF:FF:FF).

         o    Once in the DL_ATTACHED  state,  you  must  send  a
              DL_BIND_REQ  to associate a particular SAP with the
              stream.

  Configuration
     Link speed and mode can only be 10000 Mbps full-duplex.  See
     the IEEE 802.3 Standard for more information.
