Function Documentation

xran_app_fragment_packet()

int32_t xran_app_fragment_packet	(	struct rte_mbuf *	pkt_in,
		struct rte_mbuf **	pkts_out,
		uint16_t	nb_pkts_out,
		uint16_t	mtu_size,

		uint8_t *	seqid
	)

XRAN fragmentation.

This function implements the application fragmentation of XRAN packets.

Parameters

pkt_in	The input packet.
pkts_out	Array storing the output fragments.
mtu_size	Size in bytes of the Maximum Transfer Unit (MTU) for the outgoing XRAN datagrams. This value includes the size of the XRAN headers.
pool_direct	MBUF pool used for allocating direct buffers for the output fragments.
pool_indirect	MBUF pool used for allocating indirect buffers for the output fragments.

Returns

Upon successful completion - number of output fragments placed in the pkts_out array. Otherwise - (-1) * <errno>.
