proto_media_input_v2

Declaration

typedef errno_t (*proto_media_input_v2)(ifnet_t ifp, protocol_family_t protocol, mbuf_t packet);

Parameters

• ifp:

  The interface the packet was received on.

• protocol_family:

  The protocol of the packet received.

• packet:

  The packet being input.

Return Value

If the result is zero, the caller will assume the packets were passed to the protocol. If the result is non-zero and not EJUSTRETURN, the caller will free the packets.

Discussion

proto_media_input_v2 is called for all inbound packets for a specific protocol on a specific interface. This function is registered on an interface using ifnet_attach_protocolv2. proto_media_input_v2 differs from proto_media_input in that it will be called for a list of packets instead of once for each individual packet. The frame header can be retrieved using mbuf_pkthdr_header.
