This function returns the number of bytes that have been read, or a value less than zero on error. In case of an error, *packet is set to NULL.

Parameters

sock	Socket to read data from
packet	Received packet metadata and payload. src and dst should be preset.

Returns: The number of bytes received on success, or a value less than zero on error.
