) Compile the Java call class of the JNI ModuleThis is inevitable. For JNI, a caller must be able to add an original file named jnimodule. Java in the innermost directory of SRC. It looks as follows:Public class jnimodule {Static {System. loadlibrary ("aaaa ");}Public native static int jni_add (int A, int B );}Note that we will eventually generate a name called libaaaa. so's arm-compatible binary dynamic library, but in the use of system. when loadlibrary is dynamically loaded, you only need to
1. Compile the WiFi related function as module, generate Bcmdhd.ko, the module information of Bcmdhd.ko, this module depends on Cfg80211.ko and Rfkill.ko.2. Write the script, boot automatically load WiFi module.3. Use the command #ifconfig wlan0 up to turn on WiFi.

The key parameters are real parameters.Under normal circumstances, parameters should be passed to the function in order.

4-1.Python object. What are the three attributes related to all Python objects? Please briefly describe it.[Answer]All Python objects have three features: identity, type, and value.Identity: each object has a unique identity. The identity of any object can be obtained using the built-in function id. This value can be considered as the memory address of the object.Type: the object type determines what type of value the object can save, what operations
table, it is directly submitted to the layer-2 Switching Module. This is generally referred to as one-time route forwarding.
The above is a brief summary of the three-layer switch process. We can see the characteristics of the three-layer switch:
Hardware is used together to achieve high-speed data forwarding.
This is not a simple superposition of Layer 2 switch
Layer-2, layer-3, and layer-4 switches have different characteristics. layer-2 switching is a mature technology. A layer-2 switch is a data link layer device that can identify MAC address information in data packets, forward based on the MAC address, and record these MAC addresses and corresponding ports in an internal
