So that is close, but not exactly what I was asking.  Specifically
I did not mention ipoib, I want to know can I bpf dump packets at
the link layer regardless what the layer 3 protocol is.

And from reading the other email it sounds as if this "fake ethernet
header" is what is getting in the way of bpf into ipoib working.
