}

An Interface Description Block (IDB) is the container for information describing an interface on which packet data is captured.

Fields

linktype: DataLink

A value that defines the link layer type of this interface. The list of Standardized Link Layer Type codes is available in the tcpdump.org link-layer header types registry..

reserved: u16

Not used - MUST be filled with 0 by pcap file writers, and MUST be ignored by pcapng file readers.

snaplen: u32

Maximum number of octets captured from each packet. The portion of each packet that exceeds this value will not be stored in the file. A value of zero indicates no limit.

options: Vec<InterfaceDescriptionOption<'a>>
