WebTask 1 – What are Packets and Frames. Packets and frames are two ways of describing specific types of data units that are used in networking. A frame (think ‘Ethernet frame’) is used at the Data Link layer to transfer data on a network. A packet is used at the Network layer to transfer data between networks. 1) A header. WebIt defaults to the socket's protocol. * sll_ifindex is the interface index of the interface (see netdevice (7) ); 0 matches any interface (only permitted for binding). sll_hatype is an ARP type as defined in the include file. * sll_pkttype contains the packet type. Valid types are PACKET_HOST for a packet addressed to the local ...
