Struct netlink_packet_core::header::NetlinkHeader

pub struct NetlinkHeader {
    pub length: u32,
    pub message_type: u16,
    pub flags: u16,
    pub sequence_number: u32,
    pub port_number: u32,
}

A Netlink header representation. A netlink header has the following structure:

0                8                16              24               32
+----------------+----------------+----------------+----------------+
|                 packet length (including header)                  |
+----------------+----------------+----------------+----------------+
|          message type           |              flags              |
+----------------+----------------+----------------+----------------+
|                           sequence number                         |
+----------------+----------------+----------------+----------------+
|                   port number (formerly known as PID)             |

Fields

length: u32

Length of the netlink packet, including the header and the payload

message_type: u16

NetlinkMessage type. The meaning of this field depends on the netlink protocol family in use.

flags: u16

Flags. It should be set to one of the NLM_F_* constants.

sequence_number: u32

Sequence number of the packet

port_number: u32

Port number (usually set to the the process ID)
