Determine if in incoming IP packet is covered by a RAW PCB and if so, pass it to a user-provided receive callback function.
Given an incoming IP datagram (as a chain of pbufs) this function finds a corresponding RAW PCB and calls the corresponding receive callback function.
- Parameters:
-
p pbuf to be demultiplexed to a RAW PCB. inp network interface on which the datagram was received.
- Returns:
- - 1 if the packet has been eaten by a RAW PCB receive callback function. The caller MAY NOT not reference the packet any longer, and MAY NOT call pbuf_free().
- - 0 if packet is not eaten (pbuf is still referenced by the caller).
Definition at line 135 of file lwip_raw.c.
This function is called from netif.c when address is changed.
- Parameters:
-
old_addr IP address of the netif before change new_addr IP address of the netif after change
