示例1: get_current_link

/**
 * SIPC header_create() family functions
 *
 * Create SIPC5 header
 *
 * sipc5_hdr_create_skb()
 *	Create common SIPC5 header
 *
 * sipc5_hdr_create_legacy_rfs()
 *	Create SIPC5 header with IPC4.1 RFS header
 *	Because IMC modem used the 256KB rfs packet and RILD check the full
 *	packet with RFS header len, kernel remove the SIPC5 header and add the
 *	lagacy RFS header.
 *
 * sipc5_hdr_create_multifmt()
 *	TBD
 *
 * sipc5_hdr_create_skb_handover()
 *	Remove the ethernet frame When use `handover' with Network Bridge,
 *	user -> bridge device(rmnet0) -> real rmnet(xxxx_rmnet0) -> here.
 *	bridge device is ethernet device unlike xxxx_rmnet(net device).
 *	We remove the an ethernet header of skb before using skb->len,
 *	because bridge device added an ethernet header to skb.
 *
 * RETURN
 *	Returns the socket buffer that added SIPC5 header.
