Sorry for being too brief about the things I've tested. But yes, I've
tested running at 15MHz with the same or similar enough results that
I've not been able to discern any difference.
Meaningful to mention here as well would be that I've tested with and
without DMA as well.

As you assume, this was with TCP. I'll do a run with tcpdump and see if
I can compile any intelligent statistics from that.
