108 * This function is invoked by system services to initialize the LTE-RLC
109 * layer. This is an entry point used by LTE_RLC layer to initialize its
110 * global variables, before becoming operational.
112 * Allowable values for parameters are specified in ssi.h.

117 * LTE-RLC should allocate structures and buffers.
118 * @param[in] reason - Specifies the reason for calling this
119 * initialization function.
