proto_inject

Declaration

errno_t proto_inject(protocol_family_t protocol, mbuf_t packet);

Parameters

• protocol:

  The protocol of the packet.

• packet:

  The first packet in a chain of packets to be injected.

Return Value

A errno error on failure. Unless proto_inject returns zero, the caller is responsible for freeing the mbuf.

Discussion

Injects a packet on the specified protocol from anywhere. To avoid recursion, the protocol may need to queue the packet to be handled later.
