colo-compare: track connection and enqueue packet
In this patch we use kernel jhash table to track
connection, and then enqueue net packet like this:

We use conn_list to record connection info.
When we want to enqueue a packet, firstly get the
connection from connection_track_table. then push
the packet to g_queue(pri/sec) in it's own conn.
