NAME
     mcxe - Mellanox ConnectX-2 10GbE NIC Driver

SYNOPSIS
     /dev/mcxe*

DESCRIPTION
     The mcxe 10 Gigabit Ethernet  driver  is  a  multi-threaded,
     loadable, clonable, GLD-based, STREAMS driver supporting the
     Data  Link  Provider  Interface,   dlpi(7P),   on   Mellanox
     ConnectX-2 10GigE controllers.


     The mcxe driver functions include controller initialization,
     frame  transmit  and receive, promiscuous and multicast sup-
     port.

  Application Programming Interface
     The cloning character-special device, /dev/mcxe, is used  to
     access  all Mellanox ConnectX-2 10-Gigabit devices installed
     within the system.


     The mcxe driver is managed by  the  dladm(1M)  command  line
     utility.  dladm  allows  VLANs  to be defined on top of mcxe
     instances and for  mcxe  instances  to  be  aggregated.  See
     dladm(1M) for 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
     The mcxe driver performs auto-negotiation to select the link
     speed  and  mode. Link speed and mode can only be 10000 Mbps
     full-duplex. See the IEEE 802.3 Standard for  more  informa-
     tion.
