Have you looked at any of the work that the PXI group has done on NTB support within PXI? http://www.ni.com/white-paper/12523/en I was on that working group, and one of the first capabilities I suggested for it was IP over NTB - I was going to implement this at my employer, but the project took a different turn and this idea got put on the back burner. I am glad somebody else has seen fit to take it up. Also, a stupid question but one I have to ask: have you taken into account the idea that the CPUs on each side of the NTB might have different endian-ness? I was looking at a case with a PPC on one side of the bridge and an X86 on the other. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
