Currently, the probe timer is reused as the raise timer when PLPMTUD is in the Search Complete state. raise_count was introduced to count how many times the probe timer has timed out. When raise_count reaches to 30, the raise timer handler will be triggered. During the whole processing above, the timer keeps timing out every probe_ interval. It is a waste for the Search Complete state, as the raise timer only needs to time out after 30 * probe_interval. Since the raise timer and probe timer are never used at the same time, it is no need to keep probe timer 'alive' in the Search Complete state. This patch to introduce sctp_transport_reset_raise_timer() to start the timer as the raise timer when entering the Search Complete state. When entering the other states, sctp_transport_reset_probe_timer() will still be called to reset the timer to the probe timer. raise_count can be removed from sctp_transport as no need to count probe timer timeout for raise timer timeout. last_rtx_chunks can be removed as sctp_transport_reset_probe_timer() can be called in the place where asoc rtx_data_chunks is changed.
