5fac4ee9ab Cisco uses milliseconds for uptime. This is stupid. Nobody cares of such 
precision when IP packet may travel through internet for several seconds.
Also uptime measured in milliseconds overflows every 48+ days.
But we have to do same to keep compatibility with Cisco and flow-tools.

Make a macro MILLIUPTIME, which does overflowable multiplication to 1000.

d1240630b3 Expire aged flows in normal expiry thread. This fixes the problem, when 
a node disconnected from all sources of traffic never purges its cache.

6aa1da2917 In case of various tunneling protocols, mbuf may pass several interfaces 
before entering ng_netflow. In this case it will have not NULL m_pkthdr.rcvif.
However, it will enter ng_iface soon with another index. So let in_ifIndex
value configured by user override m_pkthdr.rcvif.
