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: + CompareState ++ | | +---------------+ +---------------+ +---------------+ |conn list +--->conn +--------->conn | +---------------+ +---------------+ +---------------+ | | | | | | +---------------+ +---v----+ +---v----+ +---v----+ +---v----+ |primary | |secondary |primary | |secondary |packet | |packet + |packet | |packet + +--------+ +--------+ +--------+ +--------+ | | | | +---v----+ +---v----+ +---v----+ +---v----+ |primary | |secondary |primary | |secondary |packet | |packet + |packet | |packet + +--------+ +--------+ +--------+ +--------+ | | | | +---v----+ +---v----+ +---v----+ +---v----+ |primary | |secondary |primary | |secondary |packet | |packet + |packet | |packet + +--------+ +--------+ +--------+ +--------+ 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.
