Declaration

typedef errno_t (*bpf_send_func)(ifnet_t interface, u_int32_t data_link_type, mbuf_t packet);

Parameters

• interface:

  The interface the packet is being sent on.

• dlt:

  The data link type the bpf device is attached to.

• packet:

  The packet to be sent.

Discussion

bpf_send_func is called when a bpf file descriptor is used to send a raw packet on the interface. The mbuf and data link type are specified. The callback is responsible for releasing the mbuf whether or not it returns an error.
