 * This file defines an interface for layer 2 (link layer) packet sending and
 * receiving. l2_packet_linux.c is one implementation for such a layer 2
 * implementation using Linux packet sockets and l2_packet_pcap.c another one
 * using libpcap and libdnet. When porting %wpa_supplicant to other operating
 * systems, a new l2_packet implementation may need to be added.
