Viewing the DMA transfer in Arria GX

Hi

I'm a newbie in using Altera Arria GX dev kit.

I am interested how can I take the DMA transfer from the kernel space to the userspace through the altpcichdma.ko diver?

Are there specified progs(Wireshark,...),so I could take the packet from the Arria GX through the PCIe?

Maybe the are specified function's in Linux to save,for examle,the packet in i file?

Thank's
