	Thank you for replying!
	It't quite dificult to say if the problem exists without our changes, since the all software is dependent on this changes so to work with the hardware. I can't answer to that right now on that, but I forgot to add one thing: we have ring buffer full problems on our fcc_enet driver from time to time. So, I think the problem could be on linux configurations (related to hw) because there is a lot of posts on the web related to problems similar to this (none of them has really solved the bottom problem).

Do you see these problems without the proprietary changes, and with a
current kernel?
