Vlad Yasevich 619a60ee04 sctp: Remove outqueue empty state ... The SCTP outqueue structure maintains a data chunks that are pending transmission, the list of chunks that are pending a retransmission and a length of data in flight. It also tries to keep the emtpy state so that it can performe shutdown sequence or notify user. The problem is that the empy state is inconsistently tracked. It is possible to completely drain the queue without sending anything when using PR-SCTP. In this case, the empty state will not be correctly state as report by Jamal Hadi Salim <jhs@mojatatu.com>. This can cause an association to be perminantly stuck in the SHUTDOWN_PENDING state. Additionally, SCTP is incredibly inefficient when setting the empty state. Even though all the data is availaible in the outqueue structure, we ignore it and walk a list of trasnports. In the end, we can completely remove the extra empty state and figure out if the queue is empty by looking at 3 things: length of pending data, length of in-flight data, and exisiting of retransmit data. All of these are already in the strucutre.
