Log:
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
