I'm using the latest firmwares from git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git (update today):

When I upgrade my Kernel to sys-kernel/gentoo-sources-3.12.1, I cant do a upload with more than 50-300kbps (Even in iternal LAN). Download speed is normal.

When I rollback to sys-kernel/gentoo-sources-3.10.7-r1, my upload speed is OK, but I got SEVERAL kernel logs, everytime:

Thanks for your attention.
