//
//  DESCRIPTION:
//      This function is a part of the basic RF library, but must be declared by the application. Once
//		the application has turned on the receiver, using basicRfReceiveOn(), all incoming packets will
//		be received by the FIFOP interrupt service routine. When finished, the ISR will call the
//		basicRfReceivePacket() function. Please note that this function must return quickly, since the
//		next received packet will overwrite the active BASIC_RF_RX_INFO structure (pointed to by pRRI).
//
//  ARGUMENTS:
//		BASIC_RF_RX_INFO *pRRI
//	      	The reception structure, which contains all relevant info about the received packet.
//
//  RETURN VALUE:
//     BASIC_RF_RX_INFO*
//			The pointer to the next BASIC_RF_RX_INFO structure to be used by the FIFOP ISR. If there is
//			only one buffer, then return pRRI.
