-
-addip_enable - BOOLEAN
-	Enable or disable extension of  Dynamic Address Reconfiguration
-	(ADD-IP) functionality specified in RFC5061.  This extension provides
-	the ability to dynamically add and remove new addresses for the SCTP
-	associations.
-
-	1: Enable extension.
-
-	0: Disable extension.
-
-	Default: 0
-
-addip_noauth_enable - BOOLEAN
-	Dynamic Address Reconfiguration (ADD-IP) requires the use of
-	authentication to protect the operations of adding or removing new
-	addresses.  This requirement is mandated so that unauthorized hosts
-	would not be able to hijack associations.  However, older
-	implementations may not have implemented this requirement while
-	allowing the ADD-IP extension.  For reasons of interoperability,
-	we provide this variable to control the enforcement of the
-	authentication requirement.
-
-	1: Allow ADD-IP extension to be used without authentication.  This
-	   should only be set in a closed environment for interoperability
-	   with older implementations.
-
-	0: Enforce the authentication requirement
-
-	Default: 0
-
-auth_enable - BOOLEAN
-	Enable or disable Authenticated Chunks extension.  This extension
-	provides the ability to send and receive authenticated chunks and is
-	required for secure operation of Dynamic Address Reconfiguration
-	(ADD-IP) extension.
-
-	1: Enable this extension.
-	0: Disable this extension.
-
-	Default: 0
-
-prsctp_enable - BOOLEAN
-	Enable or disable the Partial Reliability extension (RFC3758) which
-	is used to notify peers that a given DATA should no longer be expected.
-
-	1: Enable extension
-	0: Disable
-
-	Default: 1
-
-max_burst - INTEGER
-	The limit of the number of new packets that can be initially sent.  It
-	controls how bursty the generated traffic can be.
-
-	Default: 4
-
-association_max_retrans - INTEGER
-	Set the maximum number for retransmissions that an association can
-	attempt deciding that the remote end is unreachable.  If this value
-	is exceeded, the association is terminated.
-
-	Default: 10
-
-max_init_retransmits - INTEGER
-	The maximum number of retransmissions of INIT and COOKIE-ECHO chunks
-	that an association will attempt before declaring the destination
-	unreachable and terminating.
-
-	Default: 8
-
-path_max_retrans - INTEGER
-	The maximum number of retransmissions that will be attempted on a given
-	path.  Once this threshold is exceeded, the path is considered
-	unreachable, and new traffic will use a different path when the
-	association is multihomed.
-
-	Default: 5
-
-rto_initial - INTEGER
-	The initial round trip timeout value in milliseconds that will be used
-	in calculating round trip times.  This is the initial time interval
-	for retransmissions.
-
-	Default: 3000
-
-rto_max - INTEGER
-	The maximum value (in milliseconds) of the round trip timeout.  This
-	is the largest time interval that can elapse between retransmissions.
-
-	Default: 60000
-
-rto_min - INTEGER
-	The minimum value (in milliseconds) of the round trip timeout.  This
-	is the smallest time interval the can elapse between retransmissions.
-
-	Default: 1000
-
-hb_interval - INTEGER
-	The interval (in milliseconds) between HEARTBEAT chunks.  These chunks
-	are sent at the specified interval on idle paths to probe the state of
-	a given path between 2 associations.
-
-	Default: 30000
-
-sack_timeout - INTEGER
-	The amount of time (in milliseconds) that the implementation will wait
-	to send a SACK.
-
-	Default: 200
-
-valid_cookie_life - INTEGER
-	The default lifetime of the SCTP cookie (in milliseconds).  The cookie
-	is used during association establishment.
-
-	Default: 60000
-
-cookie_preserve_enable - BOOLEAN
-	Enable or disable the ability to extend the lifetime of the SCTP cookie
-	that is used during the establishment phase of SCTP association
-
-	1: Enable cookie lifetime extension.
-	0: Disable
-
-	Default: 1
-
-rcvbuf_policy - INTEGER
-	Determines if the receive buffer is attributed to the socket or to
-	association.   SCTP supports the capability to create multiple
-	associations on a single socket.  When using this capability, it is
-	possible that a single stalled association that's buffering a lot
-	of data may block other associations from delivering their data by
-	consuming all of the receive buffer space.  To work around this,
-	the rcvbuf_policy could be set to attribute the receiver buffer space
-	to each association instead of the socket.  This prevents the described
-	blocking.
-
-	1: rcvbuf space is per association
-	0: recbuf space is per socket
-
-	Default: 0
-
-sndbuf_policy - INTEGER
-	Similar to rcvbuf_policy above, this applies to send buffer space.
-
-	1: Send buffer is tracked per association
-	0: Send buffer is tracked per socket.
-
-	Default: 0
-
-sctp_mem - vector of 3 INTEGERs: min, pressure, max
-	Number of pages allowed for queueing by all SCTP sockets.
-
-	min: Below this number of pages SCTP is not bothered about its
-	memory appetite. When amount of memory allocated by SCTP exceeds
-	this number, SCTP starts to moderate memory usage.
-
-	pressure: This value was introduced to follow format of tcp_mem.
-
-	max: Number of pages allowed for queueing by all SCTP sockets.
-
-	Default is calculated at boot time from amount of available memory.
-
-sctp_rmem - vector of 3 INTEGERs: min, default, max
-	See tcp_rmem for a description.
