Depending on the value of len_proto, the function wraps the 802.1q header inside either an IEEE 802.3 header or an RFC 894 Ethernet II (DIX) header (both resulting in an 18-byte frame). If len is 1500 or less, most receiving protocol stacks parse the frame as an IEEE 802.3 encapsulated frame. If len is one of the Ethernet type values, most protocol stacks parse the frame as an RFC 894 Ethernet II encapsulated frame. Note the length value is calculated without the 802.1q header of 18 bytes. <dl compact><dt><b>Parameters:</b></dt><dd>

! 1749: Builds an RFC 1771 Border Gateway Protocol 4 (BGP-4) header. The primary function of a BGP speaking system is to exchange network reachability information with other BGP systems. This network reachability information includes information on the list of Autonomous Systems (ASs) that reachability information traverses. This information is sufficient to construct a graph of AS connectivity from which routing loops may be pruned and some policy decisions at the AS level may be enforced. This function builds the base BGP header which is used as a preamble before any other BGP header. For example, a BGP KEEPALIVE message may be built with only this function, while an error notification requires a subsequent call to libnet_build_bgp4_notification. <dl compact><dt><b>Parameters:</b></dt><dd>

It is then followed by the GRE header and finally the encapsulated packet (IP or whatever).

! 8349: Creates the libnet environment. It initializes the library and returns a libnet context. If the injection_type is LIBNET_LINK or LIBNET_LINK_ADV, the function initializes the injection primitives for the link-layer interface enabling the application programmer to build packets starting at the data-link layer (which also provides more granular control over the IP layer). If libnet uses the link-layer and the device argument is non-NULL, the function attempts to use the specified network device for packet injection. This is either a canonical string that references the device (such as "eth0" for a 100MB Ethernet card on Linux or "fxp0" for a 100MB Ethernet card on OpenBSD) or the dots and decimals representation of the device's IP address (192.168.0.1). If device is NULL, libnet attempts to find a suitable device to use. If the injection_type is LIBNET_RAW4 or LIBNET_RAW4_ADV, the function initializes the injection primitives for the IPv4 raw socket interface. The final argument, err_buf, should be a buffer of size LIBNET_ERRBUF_SIZE and holds an error message if the function fails. This function requires root privileges to execute successfully. Upon success, the function returns a valid libnet context for use in later function calls; upon failure, the function returns NULL. <dl compact><dt><b>Parameters:</b></dt><dd>

! 8793: If a given protocol header is built with the checksum field set to "0", by default libnet will calculate the header checksum prior to injection. If the header is set to any other value, by default libnet will not calculate the header checksum. To over-ride this behavior, use <a class="el" href="libnet-functions_8h.html#a13">libnet_toggle_checksum()</a>. Switches auto-checksumming on or off for the specified ptag. If mode is set to LIBNET_ON, libnet will mark the specificed ptag to calculate a checksum for the ptag prior to injection. This assumes that the ptag refers to a protocol that has a checksum field. If mode is set to LIBNET_OFF, libnet will clear the checksum flag and no checksum will be computed prior to injection. This assumes that the programmer will assign a value (zero or otherwise) to the checksum field. Often times this is useful if a precomputed checksum or some other predefined value is going to be used. Note that when libnet is initialized with LIBNET_RAW4, the IPv4 header checksum will always be computed by the kernel prior to injection, regardless of what the programmer sets. <dl compact><dt><b>Parameters:</b></dt><dd>
