WebNOTES For portable programs it is suggested to use AF_PACKET via pcap(3); although this only covers a subset of the AF_PACKET features. The SOCK_DGRAM packet sockets make no attempt to create or parse the IEEE 802.2 LLC header for a IEEE 802.3 frame. When ETH_P_802_3 is specified as protocol for sending the kernel creates the 802.3 frame and … WebCreate the AF_PACKET socket The socket that will be used to capture the Ethernet frames should be created using the socket function. This takes three arguments: the domain ( AF_PACKET for a packet socket); the socket type ( SOCK_RAW if you want to capture the Ethernet headers or SOCK_DGRAM if not); and
