Show current MAC address instead of permanent MAC address in details view
Current behavior is for the details view to show the permanent MAC address of the card. This currently creates a missunderstanding in which the user might think that the MAC address in use is, in fact, the one shown there, while this might not be the case if the MAC addres has been cloned/changed/spoofed. This leads the user to believe that the change to his MAC address did not work or to not be able to recognize his own traffic if he expect to see that MAC on sniffed traffic for example, and many other scenarios.
NOTE: the current fix is applied only to the wireless device as I am unable to test the wired device code block and would refrain from committing untested code, but it is highly advisable to add those too.
