  Log:
  Improve mxge receive performance:
  
  - Update to the latest (1.4.18) f/w.  This f/w introduces a new
    receive mode which allows us to use FreeBSD's physically discontinuous
    MJUM9BYTES clusters.
  
  - Switch the driver from chaining MJUMPAGESIZE clusters to using
    MJUM9BYTES clusters to avoid mbuf chaining overheads.  Due to this
    change, people running obsolete f/w images will be limited to an MTU of
    PAGE_SIZE - 16.
  
  - Add (disabled by default) support for Large Receive Offload.
