Now tipc socket table is statically allocated as a global variable. Through it, we can look up one socket instance with port ID, insert a new socket instance to the table, and delete a socket from the table. But when tipc supports net namespace, each namespace must own its specific socket table. So the global variable of socket table must be redefined in tipc_net structure. As a concequence, a new socket table will be allocated when a new namespace is created, and a socket table will be deallocated when namespace is destroyed.
