Enabling and Disabling DCA
 
Hi all,

I'm using Linux Kernel version 2.6.33 on a server with Intel Xeon X5570.

I assume that Intel's DCA is already enabled on my system, because I see

Code:
# dmesg | grep dca
dca service started, version 1.12.1
Am I right?

I would like to test the effects of with and without DCA. How can I disable DCA?

Thank you.

Regards,
Rayne

Can you disable it in BIOS?

I'm not sure, I haven't checked the BIOS yet.

I'm wondering if I could down all my eth interfaces, then remove the ioatdma module to disable DCA instead.
