 Without network namespaces, virtual interfaces created within the same namespace use the loopback device for packet transmission between them, as the kernel recognizes them as residing on the same host.
 
-In our testing setup, all interfaces created by vwifi are placed within an isolated network namespace. This approach ensures that each virtual interface operates independently, facilitating comprehensive testing of networking functionalities without interference from the host's network configuration.

 Below, we will conduct two separate tests: Infrastructure BSS and Independent BSS.
