	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: Work on the client code, be able to open the device	Holger Hans Peter Freyther	1	-1/+15
	Add vty code to allow changing the device, this will just attempt to open and close the device. Nothing else is done.

	This is just the normal skeleton for the osmocom code.
