That last option isn't set on other Tegra boards; what's it for?
This is my special gift to Thierry to leverage architecture specific memory copying routine which gives another few percent performance boost on image download curtsey Stefan initially experimenting with it on Vybrid (;-p).
Unfortunately enabling this doesn't seem to make much difference on Jetson TK1. TFTP downloads are still around 2 MiB/s. But I suspect that this might be a more general issue with the r8169 driver not being very optimized for speed.
