    sctp: remove prsctp_param from sctp_chunk · 0605483f
    Xin Long authored
    Now sctp uses chunk->prsctp_param to save the prsctp param for all the
    prsctp polices, we didn't need to introduce prsctp_param to sctp_chunk.
    We can just use chunk->sinfo.sinfo_timetolive for RTX and BUF polices,
    and reuse msg->expires_at for TTL policy, as the prsctp polices and old
    expires policy are mutual exclusive.
    
    This patch is to remove prsctp_param from sctp_chunk, and reuse msg's
    expires_at for TTL and chunk's sinfo.sinfo_timetolive for RTX and BUF
    polices.
    
    Note that sctp can't use chunk's sinfo.sinfo_timetolive for TTL policy,
    as it needs a u64 variables to save the expires_at time.
    
    This one also fixes the "netperf-Throughput_Mbps -37.2% regression"
    issue.
