Well that took a bit longer than I hoped thanks to some derps on my part, but I'm parsing incoming PCIe DLLPs and validating their checksums.
Next step will be to figure out that a type 0x40 DLLP with payload 074040 is actually an InitFC1-P DLLP for virtual circuit 0 for 29 headers and 1024 data bytes.
And do something useful with that information.
