2013-05-13staging: add mausezahn staging directoryDaniel Borkmann66-12/+28728
After some back and forth, we decided that it is easier to maintain mausezahn in a staging directory until it is fully reworked and cleaned up to be ready to be fully integrated. This way, it is better than having it in a separate branch, and we can also accept patches from outside more easily. Also, while at it, fix up some function mismatches with libcli.

2013-05-12flowtop: Use size of destination buffer in memcpyTobias Klauser1-1/+1

2013-05-10pcap: let netsniff-ng also record pkt timestamp sourceDaniel Borkmann1-3/+26
With commit [1] in the kernel, we can also store the timestamp source in the pcap packet header for later analysis. We do this by splitting the netsniff-ng's u32 ifindex into u16 tsource and u16 ifindex. Older kernel do not support the timestamp source in PF_PACKET, so it will stay 0 and is compatible with older netsniff-ng binaries.
