sctp: implement sctp association probing module
This patch implement sctp association probing module, the module will be called sctp_probe. This module allows for capturing the changes to SCTP association state in response to incoming packets. It is used for debugging SCTP congestion control algorithms. Usage: $ modprobe sctp_probe [full=n] [port=n] [bufsize=n] $ cat /proc/net/sctpprobe The output format is: TIME ASSOC LPORT RPORT MTU RWND UNACK <REMOTE-ADDR STATE CWND SSTHRESH INFLIGHT PARTIAL_BYTES_ACKED MTU> ... The output will be like this: 9.226086 c4064c48 9000 8000 1500 53352 1 *192.168.0.19 1 4380 54784 1252 0 1500 9.287195 c4064c48 9000 8000 1500 45144 5 *192.168.0.19 1 5880 54784 6500 0 1500 9.289130 c4064c48 9000 8000 1500 42724 5 *192.168.0.19 1 7380 54784 6500 0 1500 9.620332 c4064c48 9000 8000 1500 48284 4 *192.168.0.19 1 8880 54784 5200 0 1500 ......
