> Now sctp uses chunk->resent to record if a chunk is retransmitted, for
> RTT measurements with retransmitted DATA chunks. chunk->sent_count was
> introduced to record how many times one chunk has been sent for prsctp
> RTX policy before. We actually can know if one chunk is retransmitted
> by checking chunk->sent_count is greater than 1.
> This patch is to remove resent from sctp_chunk and reuse sent_count
> to avoid retransmitted chunks for RTT measurements.
