  SVN rev 197395 on 2009-09-21 20:16:10Z by gallatin
  
  Improve mxge watchdog routine's ability to reliably reset a failed NIC:
  
  - Mark the link as down, so if watchdog reset fails, link watching
      failover software can notice it
  - Don't send MXGEFW_CMD_ETHERNET_DOWN if the NIC has been reset, it is
      not needed, and will fail on a freshly reset NIC.
  - Ensure the transmit routines aren't attempting to PIO write to doorbells
      while the NIC is being reset.
  - Download the correct f/w, rather than using the EEPROM f/w after reset.
  - Export a count of the number of watchdog resets via sysctl
  - Zero all f/w stats at reset.  This will lead to less confusing
      diagnostic output when investigating NIC failures.
