* iq_txshift: corresponds to the value that will be used to shift the bits of I/Q samples in TX path and is dependent on the output fromat of the radio hardware target attached to RRH GW
* tx_sample_advance and tx_scheduling_advance are the parameters used for timestamp adjustment between the radio hardware target and its host
* tx_sample_advance and tx_scheduling_advance are parameters used for timestamp adjustment between the radio hardware target and its host and they depend on the radio hardware target used and the bandwidth
* tx_sample_advance-> fine-grain parameter - each unit corresponds to a sample
* tx_scheduling_advance-> coarse-grain parameter-each unit corresponds to one packet
