A device’s execute management command function is used to implement miscellaneous wireless management functionality such as scanning for available wireless network.
Files
Every wireless device driver’s net_dev.c
Prototype
Note that since every device driver’s MgmtDemux() function is accessed only by function pointer via the device driver’s API structure, it doesn’t need to be globally available and should therefore be declared as ‘static’.
