Allow to inspect UDP messages and check for GPRS, NS, BSSGP and then filter LLC frames. Parsing the vL datastructure with the libpcap syntax is a pain. It could be done using BPF but we do not want to use bpf asm to specify the entire ruleset. I looked into using libepan/libwireshark but this has memory issues and is painful too. So let's parse UDP, NS, BSSGP using the info we already have. I tried a bit of editcap to generate a bit of broken data. The length check might still be bad. I used my crash_20100602.pcap file to count the LLC frames we detect and compare that to wireshark it ended with the right number. pcap add-filter gprs can be used to enable the new filtering option after the OS has received the packet.
