Help¶

For AF_PACKET sockets with SOCK_DGRAM type, the L2 header is removed before the packet is passed to the user. Packets sent through a SOCK_DGRAM packet socket get a suitable L2 header based on the information in the sockaddr_ll destination address before they are queued.

Direct dependencies¶

NET_SOCKETS_PACKET && NET_SOCKETS && NETWORKING

(Includes any dependencies from ifs and menus.)
