size_t net_pkt_get_payload_offset

(

const struct net_pkt *const

packet

)

Get the offset of the IP payload in the given packet.

The payload begins after the innermost IP header (and its extension headers).

Parameters

packet

The packet to get the payload offset for

Returns

The payload offset (in bytes)

bool net_pkt_parse	(	struct net_pkt *const	packet,
		const struct rohc_buf	data,
		rohc_trace_callback2_t	trace_cb,
		void *const	trace_cb_priv,
		rohc_trace_entity_t	trace_entity
	)

Parse a network packet.

Parameters

[out]	packet	The parsed packet
	data	The data to parse
	trace_cb	The function to call for printing traces
	trace_cb_priv	An optional private context, may be NULL
	trace_entity	The entity that emits the traces

Returns

true if the packet was successfully parsed, false if a problem occurred (a malformed packet is not considered as an error)
