As these operations are pretty complex, they easily involve fatal mistakes. If these sk_buff pointers are replaced with sk_buff_head instances as queue heads and corresponding generic SKB list APIs are used to manage them, the entire TIPC code would become quite clean and readable. But before make the change, we need to clean up below redundant functionalities: - remove node subscribe infrastructure - remove protocol message queue - remove retransmission queue - clean up process of pushing packets in link layer ==================== Signed-off-by: David S.
