DMA xmit from kernel space to pci device memory
I want to do a DMA xmit from the kernel memory space to the memory on a pcie device.
I want to use the DMA channel on the motherboard (Not the DMA on the PCI device).
At all the reference code that I looked at they used the device DMA and they sends one address. In xmit it is the source, where is the dest address?
