On Jetson TK1, this makes my "dhcp zImage" on my USB ethernet dongle got from ~1.7MiB/s to ~2.8MiB/s :-)

Very well indeed. As mentioned before Stefan discovered this working on Vybrid where we saw similar speed-up when booting from NAND flash.

I just noticed this not having been applied anywhere yet. Is the tegra tree eventually gona be re-based and this being applied?
