Fields

Field	Type	Default	Auto	Description
`src_port`	`uint(16)`	`49152`		Source port.
`dst_port`	`uint(16)`	`9`		Destination port.
`verification_tag`	`uint(32)`	`0`		Verification tag: the peer’s initiate tag (0 in a packet carrying INIT).
`checksum`	`uint(32)`		CRC-32C over the header and everything after it	CRC32c of the whole SCTP packet with this field zeroed (Auto), sent least significant octet first.
`chunks`	`tlv` — rest of the PDU	1 items		Chunks (8-bit type, 8-bit flags, 16-bit length including the 4-octet header, zero padding to 4 octets): DATA, INIT, INIT ACK, SACK, HEARTBEAT, ABORT, SHUTDOWN, ERROR, COOKIE ECHO / ACK, AUTH, I-DATA, ASCONF, RE-CONFIG, FORWARD TSN, PAD. Lengths, padding and SACK counts are Auto.

`chunks`

Type 8 bits, length 16 bits.
The length counts the type and length fields too.
The first 1 value octets sit between the type and the length.
Each item is zero-padded to a multiple of 4 octets (not counted in the length)
Unknown types are kept as raw value octets.
