*
* - No text appears between the offset and the bytes (any bytes appearing after
* such text would be ignored)
*
- * - The offset must be arithmetically correct, i.e. if the offset is 00000020, then
- * exactly 32 bytes must have been read into this packet before this. If the offset
- * is wrong, the packet is immediately terminated
+ * - The offset must be arithmetically correct, i.e. if the offset is 00000020,
+ * then exactly 32 bytes must have been read into this packet before this.
+ * If the offset is wrong, the packet is immediately terminated
*
* A packet start is signaled by a zero offset.
*
*
* The output is a libpcap packet containing Ethernet frames by
* default. This program takes options which allow the user to add
- * dummy Ethernet, IP and UDP or TCP headers to the packets in order
+ * dummy Ethernet, IP and UDP, TCP or SCTP headers to the packets in order
* to allow dumps of L3 or higher protocols to be decoded.
*
* Considerable flexibility is built into this code to read hexdumps
* hexdump line is dropped (including mail forwarding '>'). The offset
* can be any hex number of four digits or greater.
*
- * This converter cannot read a single packet greater than 64KiB-1. Packet
- * snaplength is automatically set to 64KiB-1.
+ * This converter cannot read a single packet greater than
+ * WTAP_MAX_PACKET_SIZE_STANDARD. The snapshot length is automatically
+ * set to WTAP_MAX_PACKET_SIZE_STANDARD.
