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.
