  Log:
  Update the mxge driver.
  
  - Update the firmware to the latest released firmware
    (1.4.3), which corresponds to the firmware in the
    latest shipping drivers from Myricom.  This firmware
    fixes several bugs in the firmware's PCI-e implementation,
    and it also changes the driver/firmware interface:
  
    o TSO was added, and changed the format of the transmit
      descriptors.
    o The firmware no longer counts transmits descriptors,
      but frames.  So the driver needs to keep a count
      of the number of frames sent.
    o The weird interrupt strategy changed to a normal receive
      return ring.  This ring is much bigger, and we may be
      able to support DEVICE_POLLING.
    o Myricom's header files changed the name of firmware
      related #define's and enums (s/_MCP_/FW_).
  
  - Stopped spamming the console with lots of printfs unless
    mxge_verbose (or bootverbose) is set.
  
  - Made additional information available via sysctl, including
    the results of a PCI-e DMA benchmark run at device reset.
  
  - Decreased the excessively long timeouts when sending commands
    from 2 seconds to 20ms.
