◆ SCTP_MAX_DATA_CHUNKS

#define SCTP_MAX_DATA_CHUNKS 16

max number of DATA chunk payloads tracked per packet

Definition at line 43 of file decode-sctp.h.

◆ SCTP_MAX_TRACKED_CHUNKS

#define SCTP_MAX_TRACKED_CHUNKS 16

max number of chunks tracked per packet for detection/logging value chosen to keep per-packet overhead low while still allowing some room to track chunks. SCTP has no hard limit on the number of chunks per packet. A packet can carry as many chunks as fit within the MTU, though in practice most packets contain only a few chunks.
