Fields from Ethernet packet (dest/source hardware address,  protocol, frame size, start of the Ethernet packet in Ethernet controller) are stored in this structure. These values are later used from upper layer protocols (IP, ARP). See <a class="el" href="structethernet__frame.html">ethernet_frame</a> definition for more information about struct fields.

Fields from Ethernet packet (dest/source hardware address,  protocol, frame size) are stored in this structure by the upper layer protocols (IP, ARP, other). These values are  then used for initializing transmission of an Ethernet frame.

Various fields from the IP packet are stored in this structure. These values are filled based on the information supplied by the upper  layer protocols (ICMP, UDP, TCP and possibly others) and used to form a correct IP packet (correct filed values, checksum,..).

Various fields from the TCP packet are stored in this variable. These values are then used to perform the necessary actions as defined  by the TCP specification: correctnes of the received TCP packet is checked by analyzing these fields, appropriate socket data is adjusted and/or control packet is sent based on it. See <a class="el" href="structtcp__frame.html">tcp_frame</a> definition  for struct information.
