====================
sctp: support SCTP_FUTURE/CURRENT/ALL_ASSOC
This patchset adds the support for 3 assoc_id constants: SCTP_FUTURE_ASSOC
SCTP_CURRENT_ASSOC, SCTP_ALL_ASSOC, described in rfc6458#section-7.2:
All socket options set on a one-to-one style listening socket also
apply to all future accepted sockets. For one-to-many style sockets,
often a socket option will pass a structure that includes an assoc_id
field. This field can be filled with the association identifier of a
particular association and unless otherwise specified can be filled
with one of the following constants:
SCTP_FUTURE_ASSOC: Specifies that only future associations created
after this socket option will be affected by this call.
SCTP_CURRENT_ASSOC: Specifies that only currently existing
associations will be affected by this call, and future
associations will still receive the previous default value.
SCTP_ALL_ASSOC: Specifies that all current and future associations
will be affected by this call.
The functions for many other sockopts that use assoc_id also need to be
updated accordingly.
