The only documentation is in a bunch of files in the tarball at

        http://www.tcpdump.org/release/libpcap-1.1.1.tar.gz

(i.e., the source *is* the documentation).

What sort of "AAL2 packets" do you get from the card driver?  Does it just pass you raw ATM cells, or does it pass you 
CPS packets?

I'm assuming from "RLC/MAC frames" that this is LTE traffic.  Is that the case?
