	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. Fixes: ONW#1314

2011-05-31	osmo-pcap-client: Do not print the strings if they are NULL	Holger Hans Peter Freyther	1	-8/+16
	this makes glibc add the (null) for us, but we don't want that as we would attempt to compile a filter or open a device with that.
2011-05-31	osmo-pcap-client: Work on the client code, be able to open the device	Holger Hans Peter Freyther	1	-0/+108
	Add vty code to allow changing the device, this will just attempt to open and close the device. Nothing else is done.
2011-05-31	osmo_pcap_client: Start with the framework for the pcap client	Holger Hans Peter Freyther	1	-0/+23
	This is just the normal skeleton for the osmocom code.
