Function Documentation

xran_build_ecpri_hdr()

int xran_build_ecpri_hdr	(	struct rte_mbuf *	mbuf,
		uint8_t	CC_ID,
		uint8_t	Ant_ID,
		uint8_t	seq_id,
		struct xran_ecpri_hdr **	ecpri_hdr
	)

Build ECPRI header and returns added length.

Parameters

mbuf	The pointer of the packet buffer to be parsed
CC_ID	Component Carrier ID for this C-Plane message
Ant_ID	Antenna ID(RU Port ID) for this C-Plane message
seq_id	Sequence ID for this C-Plane message
ecpri_hdr	The pointer to ECPRI header

Returns

added payload size on success XRAN_STATUS_RESOURCE if failed to allocate the space to packet buffer
