It offers the following 20 services to its users: 21 22 -- acknowledged error-free non-duplicated transfer of user data, 23 -- data fragmentation to conform to discovered path MTU size, 24 -- sequenced delivery of user messages within multiple streams, 25 with an option for order-of-arrival delivery of individual user 26 messages, 27 -- optional bundling of multiple user messages into a single SCTP 28 packet, and 29 -- network-level fault tolerance through supporting of multi- 30 homing at either or both ends of an association." 31 32 To compile this protocol support as a module, choose M here: the 33 module will be called sctp. 34 35 If in doubt, say N. 36 37if IP_SCTP 38 39config SCTP_DBG_MSG 40 bool "SCTP: Debug messages" 41 help 42 If you say Y, this will enable verbose debugging messages. 43 44 If unsure, say N.
