I'm using supermicro X8DTH-6F motherboard +2x Xeon(R) CPU L5640 @ 2.27GHz and Intel® 82599EB 10 Gigabit Ethernet Controller
kernel version 2.6.37+ixgbe-3.2.10
ioatdma and dca enabled in bios and in kernel

root@servername:~# lsmod|grep ioat
ioatdma 33088 48
dca 4354 2 ixgbe,ioatdma

root@servername:~# dmesg |grep dca
[ 19.762295] dca service started, version 1.12.1

    dca may not be enabled in your processor MSRs, as the bios might be buggy.
