Function for extracting all IQ samples from xRAN packet holding a single data section.

Function extracts IQ samples from received mbuf packet.

Parameters

iq_data_start	Address of the first element in IQ data array.
symb_id	Symbol ID to be extracted from ecpri header
seq_id	Sequence ID to be extracted from radio header

Returns

int Size of remaining mbuf filled with IQ samples zero on failure
