Yes, absolutely. As long as the caveat is understood, feel free to add
Tested-by: David Woodhouse <David.Woodhouse@...el.com>

I did look through the datasheet to see if there's anything we can do to
improve reception of large packets. We could try to reduce the Rx Fifo
threshold, which we currently set at 512 bytes... but it isn't going to
get us much further on this particular hardware. Might be nice to have
it tunable though.

There's a v1.6 datasheet at http://realtek.info/pdf/rtl8139cp.pdf btw.
