 This function does the de-allocation of the queues allocated for the transmit and the receive of the Subscriber Station

+[source:/ResearchApps/MAC/WANMAC/Subscriber/substation.c@301#L76 ackmac_main]
+The first funtion to be called when the program begins the execution. It extracts the last byte of the MAC Address. This
+allocates the Memmory Buffer for the program . It then calls the function for Hardware Initialisation, followed by the
+Software Initialization and finally triggering off the State Machine.

+[source:/ResearchApps/MAC/WANMAC/Subscriber/substation.c@301#L76 RxSSPDUs]
+This function waits in a while loop till the timer goes off on the global variable notEndRxPDU. It expects to receive packets from
+the Base Station during this time interval. Note the setting of the timer is not done in this function unlike the Base Station, instead
+it is done in the state machine itself just after reading the Maps.

+[source:/ResearchApps/MAC/WANMAC/Subscriber/substation.c@301#L76 TxSSPDUs]
+This function keeps on calling the function to remove packets from the transmit queue and sending them to the physcial layer. It
+waits on the global variable notEndTxPDU, which again is set in the state machine and not inside this function.
