| Function    : grr_validate_ma_num_in_freq_par

| Description : Validates MA_NUM in indirect encoding.
|               This validation is required only when
|               freq parameters are received with indirect
|               encoding.
|               Change mark received with Frequency parameters is compared
|               with the stored change mark for PSI2/PSI13/SI13 to determine
|               if the mobile allocation stored in these messages could be used.
|
|               Frequency parameters received in an assignment message could refer
|               to GPRS mobile allocation received in a previous assignment message
|               by using MA_NUM = 15 in indirect encoding. Frequency parameters
|               received in non-assignment message( For example PSI 8 or PSI 14)
|               cannot refer to GPRS mobile received in a previous message.
|               This validation is done using the second parameter.
|
|               This function should be used before using the GPRS mobile allocation
|               referred in freq_par.
| Parameters  : freq_par - points to the frequency parameter structure
|               received in system information/some assignment message.
|
|               msg_type - identifies the type of message in which freq par
|                          was received. Two values are possible.

| Function    : grr_get_ref_list_or_cell_allocation
+------------------------------------------------------------------------------
| Description : Determining the frequency list to be used for a hopping channel
|               involvs following steps.
|               1. Determining the referenced set of reference frequency lists
|                  or cell allocation.( See 3GPP 04.60 12.10a)
|               2. Filtering this list based on MA_BITMAP and ARFCN index list.
|
|               This function performs the first step. ie it generates
|               the referenced set of referncelists or Cell allocation list
|               depending on the presence of RFL number list in
|               the GPRS Mobile allocation IE.
| Parameters  : list1 - output, This is list will hold the referenced set of
|               reference freq list or Cell allocation depending on the
|               contents of gp_ma passed.
|               gp_ma - pointer to gprs mobile allocation IE
|               ma_num - identifies the MA_NUM in freq parameters IE.
|                        3GPP 04.60 Sec 5.5.1.7
