SCTP stack (RFC4960)
== CONTENT == * SCTP chunks definition as per RFC4960; * Helper functions to set/get values to/from the corresponding chunks; * Hooks to the session/application layers; * Complete state-machine handling; * Implementation for unexpected chunk received in a certain state (state-machine error handling) * Support for 1-single connection; * Sample application to test receive/transmit data-path; * Test to validate SCTP stack; Change-Id: I1b55c455ab400be9513f4e094dadfc3181d2ebc9 Signed-off-by: Marco Varlese <marco.varlese@suse.com>
