mxge cleanups:

- Remove code to use the special wc_fifo.  It has been disabled by default
  in our other drivers as it actually slows down transmit by a small amount

- Dynamically determine the amount of space required for the rx_done
  ring rather than hardcoding it.

- Compute the number of tx descriptors we are willing to transmit per
  frame as the minimum of 128 or 1/4 the tx ring size.

- Fix a typo in the tx dma tag setup which could lead to unnecessary
  defragging of TSO packets (and potentially even dropping TSO packets
  due to EFBIG being returned).

- Add a counter to keep track of how many times we've needed to
  defragment a frame.  It should always be zero.

- Export new extended f/w counters via sysctl
