Subject: [PATCH net-next-2.6 v5 4/5] sctp: Add ADD/DEL ASCONF handling at the receiver

This patch fixes the problem that the original code cannot delete the remote address where the corresponding transport is currently directed, even when the ASCONF is sent from the other address (this situation happens when the single-homed sender transmits  ASCONF with ADD and DEL.)
