sctp: use SCTP_FUTURE_ASSOC and add SCTP_CURRENT_ASSOC for SCTP_DEFAULT_SEND_PARAM sockopt
Check with SCTP_ALL_ASSOC instead in sctp_setsockopt_default_send_param and check with SCTP_FUTURE_ASSOC instead in sctp_getsockopt_default_send_param, it's compatible with 0. SCTP_CURRENT_ASSOC is supported for SCTP_DEFAULT_SEND_PARAM in this patch. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
