Mark Johnston 160e7a4c16 wg: Add netmap support ... When in netmap (emulated) mode, wireguard interfaces prepend or strip a dummy ethernet header when interfacing with netmap. The netmap application thus sees unencrypted, de-encapsulated frames with a fixed header. In this mode, netmap hooks the if_input and if_transmit routines of the ifnet. Packets from the host TX ring are handled by wg_if_input(), which simply hands them to the netisr layer; packets which would otherwise be tunneled are intercepted in wg_output() and placed in the host RX ring. The "physical" TX ring is processed by wg_transmit(), which behaves identically to wg_output() when netmap is not enabled, and packets appear in the "physical" RX ring by hooking wg_deliver_in().
