NAME
     ixgbe - Intel 10Gb PCI Express NIC Driver

SYNOPSIS
     /dev/ixgbe*


DESCRIPTION
     The ixgbe Gigabit  Ethernet  driver  is  a   multi-threaded,
     loadable,  clonable, GLD-based STREAMS driver supporting the
     Data Link Provider Interface,  dlpi(7P),   on   Intel  82598
     10-Gigabit Ethernet controllers.


     The ixgbe driver functions include  controller   initializa-
     tion,  frame transmit and receive, promiscuous and multicast
     support, and error recovery and reporting.


     The ixgbe driver and  hardware support  auto-negotiation,  a
     protocol specified by the IE 802.3ae specification.

APLICATION PROGRAMING INTERFACE
     The cloning character-special device, /dev/ixgbe, is used to
     access  all  Intel  82598  10  -Gigabit  Ethernet    devices
     installed within the system.


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


     You must send an explicit DLATACHREQ message to associate
     the opened stream with a particular device (PA). The PA ID
     is interpreted as an unsigned integer data type  and   indi-
     cates  the  corresponding device instance (unit) number. The
     driver returns an error (DLERORACK)  if   the  PA  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 DLINFOACK  primi-
     tive in response to your DLINFOREQ are:

         o    Maximum SDU is 16366.

         o    Minimum SDU is 0.

         o    DLSAP address length is 8.

         o    MAC type is DLETHER.

         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/IE broad-
              cast address (F:F:F:F:F:F).

              Once in the DLATACHED  state,  you  must  send  a
              DLBINDREQ  to associate a particular SAP with the
              stream.

CONFIGURATION
     By default, the  ixgbe driver performs  auto-negotiation  to
     select the link speed and mode. Link speed and mode can only
     be 10000 Mbps full-duplex. See the IE802.3  standard   for
     more information.
