I tried 1.8, but that fails to initialize my device and fails at the pci probe:
    "Cause: Requested device 0000:04:00.1 cannot be used"
Can't even compile 2.0rc2 atm, getting:
"/usr/lib/gcc/x86_64-linux-gnu/4.6/include/emmintrin.h:701:1: note:
expected '__m128i' but argument is of type 'int'"
For reasons I don't understand.

As for the example apps (in 1.7), I can run them properly but I don't
think any of them do the same processing as I do. Note that mine does
work with most packets.
