在我们带有igb版本4.1.2的R610上,我确实看到ioatdma模块加载(并加载了lsmod)：
ioatdma: Intel(R) QuickData Technology Driver 4.00 ioatdma 0000:00:16.0: irq 80 for MSI/MSI-X ioatdma 0000:00:16.1: irq 81 for MSI/MSI-X ioatdma 0000:00:16.2: irq 82 for MSI/MSI-X ioatdma 0000:00:16.3: irq 83 for MSI/MSI-X ioatdma 0000:00:16.4: irq 84 for MSI/MSI-X ioatdma 0000:00:16.5: irq 85 for MSI/MSI-X ioatdma 0000:00:16.6: irq 86 for MSI/MSI-X ioatdma 0000:00:16.7: irq 87 for MSI/MSI-X@H_502_4@我们有一个四端口Intel nic应该支持它：
07:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) 07:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) 08:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) 08:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)@H_502_4@但是,它似乎没有用于任何网络流量：
[root@or-rtlb01 ~]# cat /sys/class/dma/dma*/bytes* 0 0 0 0 0 0 0 0@H_502_4@有谁知道如何制作它所以ioat用于网络流量？ @H_502_4@内核是Linux or-rtlb01.ds.stackexchange.com 3.7.7-1.el6.elrepo.x86_64#1 SMP Mon Feb 11 22:28:07 EST 2013 x86_64 x86_64 x86_64 GNU / Linux
