Initialize nr_prach_info_t structure to zero before use

This commit ensures that the 'info' structure is properly initialized

This prevents the use of uninitialized memory which could contain
contain garbage values.

e.g. in FR2 case we have: `info.N_RA_sfn += count_bits64(info.s_map);`

 ## Configure your server
 
-To set up the L1 and install the components manually refer to this [instructions page](https://docs.nvidia.com/aerial/cuda-accelerated-ran/index.html).
+The first step is to obtain the NVIDIA Aerial SDK, you'll need to request access [here](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/aerial-sdk).
+
+After obtaining access to the SDK, you can refer to [this instructions page](https://docs.nvidia.com/aerial/aerial-ran-colab-ota/current/index.html) to setup the L1 components using NVIDIAs' SDK manager, or to [this instructions page](https://docs.nvidia.com/aerial/cuda-accelerated-ran/index.html) in order to setup and install the components manually.
+
+The currently used Aerial Version is 24-1, which is also the one currently used by the SDK Manager.

-### Possible problems
-
-On some systems with specific ASan versions, executing a program compiled with
-ASan might fail with an error `DEADLYSIGNAL`, or simply a segmentation fault.
-Note that since OAI compiles and runs some programs _during compilation_ (for
-code generation), typically already the build is impacted.
-
-The issue is related to Address Space Layout Randomization (ASLR) settings
-in Linux, a security feature designed to make it more difficult for attackers
-to predict the locations of processes in memory.  In this case, it is possible
-to avoid the bug by running
-
-```
-sudo sysctl vm.mmap_rnd_bits=30

 ## Undefined Behavior Sanitizer (UBSAN)
 [Undefined Behavior Sanitizer](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html) (UBSAN) is a runtime undefined behavior checker. It uses compile-time instrumentation to catch undefined behavior by inserting code that performs specific checks before operations that may cause it. UBSAN can be activated with the `--sanitize-undefined` option or `-fsanitize=undefined`.

-# Time management module
-
-[[_TOC_]]
-
-## Introduction
-
-Several parts of the 4G/5G protocol stack keep track of time, for example
-for timeout events (in RRC, PDCP, or RLC for example).
-
-The obvious simple way to deal with time is to use the computer's realtime
-clock. This works well when we run the stack in realtime, with real
-radio equipment. But in simulation the system may run faster or slower
-than realtime, so we need another way to deal with time. A good solution
-is then to base time on the current IQ data processed by the system. So time
-becomes "IQ samples" based, not realtime.
-
-The system may be decomposed into various components (CU, DU, RU, various
-UEs) running either in realtime or simulation. Time may be distributed
-to all these components from only one time source for accurate execution
-of the scenario, or each component may have its own time source, either
-based on realtime or IQ samples.
-
-## Overall structure
-
-The time management module is made of three main parts. The first one
-is the time source. It can either be realtime or "IQ samples" based.
-In one running scenario of the system, there can be one or more time
-sources (imagine one for the gNB, and one per each UE). There can also
-be only one time source, shared between various users of the time
-manager.
-
-The second part is the server. One server is attached to one time source
-and receives a tick every millisecond (real or simulated) from the time
-source. It distributes the tick to the various connected clients.
-
-And finally the last part is the client, which connects to a single server
-and receives ticks from it. The client does not have a time source attached
-to it. It gets the time from the server.
-
-It is possible for a program (monolithic gNB for example) to have only
-a time source, without server or client.
-
-## Configuration
-
-To configure the time management module, add the following section in
-the configuration file.
-
-```
-time_management = {
-  #valid time sources: realtime, iq_samples
-  time_source = realtime
-
-  #valid modes: standalone, server, client
-  mode = standalone
-
-  #set ip/port of server (for server mode, this is the address/port to bind to;
-  #for client mode, this is the address/port to connect to)
-  server_ip = "127.0.0.1"
-  server_port = 7374
-}
-```
-
-If not set in the configuration file, some default is applied, depending
-on the program run. (See the function `time_manager_start()` for details.)
-
-It is also possible to pass configuration parameters on the command line.
-For example add `--time_manager.time_source iq_samples` to the command line
-to set the time source to `iq_samples`. The same syntax is applicable to the
-other parameters.
-
-## Examples
-
-Here come some examples of configuration for typical use cases of OAI.

-This is a very simple example. The gNB runs in `standalone` mode with
-a `realtime` time source.
-
-```
-time_management = {
-  time_source = realtime
-  mode = standalone
-}
-```
-### Monolithic gNB "IQ samples time"
-
-For this configuration, it's the same as the previous example, but the
-time source is now `iq_samples`.
-
-```
-time_management = {
-  time_source = iq_samples
-  mode = standalone
-}
-```
-### RF simulator CU/DU "IQ samples time"
-
-Let's suppose the CU runs on a machine with IP address 1.2.3.4 and the DU
-runs on a machine with IP address 10.11.12.13.
-
-The DU has the time source and so is the server. The CU acts as a client.
-
-Here comes the configuration for the CU.
-
-```
-time_management = {
-  mode = client
-  server_ip = "10.11.12.13"
-  server_port = 7374
-}
-```
-And here is the configuration for the DU.
-
-```
-time_management = {
-  time_source = iq_samples
-  mode = server
-  server_ip = "10.11.12.13"
-  server_port = 7374
-}
-```
-
-### RF simulator CU/DU "realtime"
-
-Let's suppose the CU runs on a machine with IP address 1.2.3.4 and the DU
-runs on a machine with IP address 10.11.12.13.
-
-CU and DU can both run in standalone mode, with no exchange between them.
-Any one of them can also acts as a server and the other one as a client.
-
-Let's suppose for this example that the CU and the DU run in client/server
-mode. Let's set the CU as the time source and so as the server. The DU acts
-as a client.
-
-Here comes the configuration for the CU.
-
-```
-time_management = {
-  time_source = realtime
-  mode = server
-  server_ip = "1.2.3.4"
-  server_port = 7374
-}
-```
-And here is the configuration for the DU.
-
-```
-time_management = {
-  mode = client
-  server_ip = "1.2.3.4"
-  server_port = 7374
-}
-```
-
-Note that the time management module is flexible. It's possible to
-configure more complex setups. For example the time source can be a gNB
-and several UEs can be connected as client.
-
-One could also write a simple program acting as a time source and distributing
-time to everyone (one or several gNB, several UEs).
-
-## Programming API
-
-Here comes the internal API of the time manager module. The (simpler) OAI
-API is described afterwards.
-
-### Time source
-
-- opaque type: `time_source_t`
-- create a time source:
-  ```
-    time_source_t *new_time_source(time_source_type_t type)
-  ```
-  where `type` is one of:
-  * `TIME_SOURCE_REALTIME`
-  * `TIME_SOURCE_IQ_SAMPLES`
-- delete a time source:
-  ```
-    void free_time_source(time_source_t *time_source)
-  ```
-- set millisecond callback:
-  ```
-    void time_source_set_callback(time_source_t *time_source,
-                                  void (*callback)(void *),
-                                  void *callback_data)
-  ```
-  where `callback` is a function that will be called for each millisecond using
-  the provided `callback_data`
-- for IQ samples time management, the user of the time source must call
-  this function when it processes IQ samples:
-  ```
-    void time_source_iq_add(time_source_t *time_source,
-                            uint64_t iq_samples_count,
-                            uint64_t iq_samples_per_second)
-  ```
-  then the time source will generate a tick for each block for IQ samples
-  lasting one millisecond. (If you pass `iq_samples_count` lasting several
-  milliseconds then the time source will generate several ticks in a row,
-  one for each millisecond.)
-
-### Server
-
-- opaque type: `time_server_t`
-- create a server:
-  ```
-    time_server_t *new_time_server(const char *ip,
-                                   int port,
-                                   void (*callback)(void *),
-                                   void *callback_data)
-  ```
-  where ip/port is the IP adress and port the server will listen to
-  and `callback` is a function that will be called for each millisecond using
-  the provided `callback_data`
-- delete a server:
-  ```
-    void free_time_server(time_server_t *time_server)
-  ```
-- attach a time source:
-  ```
-    void time_server_attach_time_source(time_server_t *time_server,
-                                        time_source_t *time_source)
-  ```
-
-### Client
-
-- opaque type: `time_client_t`
-- create a client:
-  ```
-    time_client_t *new_time_client(const char *server_ip,
-                                   int server_port,
-                                   void (*callback)(void *),
-                                   void *callback_data)
-  ```
-  the client will connect on given server ip/port
-  and use the `callback` with `callback_data` for each tick received
-- delete a client:
-  ```
-    void free_time_client(time_client_t *time_client)
-  ```
-
-### Threading
-
-Each component (time source, server, client) runs its own thread which will
-be the one calling the configured callback. Be careful of using proper
-synchronization techniques in your callback to have correct behavior with
-the other threads of the program.
-
-## OAI API
-
-OAI uses the time manager through a simplified API. All the code is contained
-in `time_manager.c`, together with some global variables (so that there is no
-need to pass objects around, to limit risks of misuse).
-
-Each program (for example: gnb, ue, cu, du) calls the `time_manager_start()`
-function, passing the callback functions to be called when a tick is generated
-(several callbacks can be passed) and a default time source. Based on this,
-`time_manager_start()` initializes what is needed.
-
-The function `time_manager_iq_samples()` is to be called by programs that
-read IQ samples. It is called unconditionally. It may do nothing if the
-configuration is to use realtime ticks and not IQ samples ticks.
-
-When the program exits, it calls `timer_manager_finish()` which in turns stops
-the various threads created by `time_manager_start()` and releases all the
-allocated data.
-
-Here comes the API.
-
-- init the time manager:
-  ```
-    void time_manager_start(time_manager_tick_function_t *tick_functions,
-                            int tick_functions_count,
-                            time_source_type_t time_source);
-  ```
-  (for valid values of `client_type` and `running_mode`  see in
-  `time_manager.h`)
-- update IQ samples' based time manager:
-  ```
-    void time_manager_iq_samples(uint64_t iq_samples_count,
-                                 uint64_t iq_samples_per_second)
-  ```
-- terminate the time manager:
-  ```
-    void time_manager_finish(void)
-  ```
