This patchset mainly adds the Event Subscription sockopt described in
rfc6525#section-6.2:
"Subscribing to events as described in [RFC6458] uses a setsockopt()
call with the SCTP_EVENT socket option. This option takes the
following structure, which specifies the association, the event type
(using the same value found in the event type field), and an on/off
boolean.
struct sctp_event {
sctp_assoc_t se_assoc_id;
uint16_t se_type;
uint8_t se_on;
};
The user fills in the se_type field with the same value found in the
strreset_type field, i.e., SCTP_STREAM_RESET_EVENT. The user will
also fill in the se_assoc_id field with either the association to set
this event on (this field is ignored for one-to-one style sockets) or
one of the reserved constant values defined in [RFC6458]. Finally,
the se_on field is set with a 1 to enable the event or a 0 to disable
the event."
As for the old SCTP_EVENTS Option with struct sctp_event_subscribe,
it's being DEPRECATED.
