Is it possible to add the feature to get the permanent MAC address in this project?

Hi, in the wifiphisher project we may want to spoof our MAC address, but after the process is done, we want to recover the adapters' MAC addresses. 

In the macchanger project, it can get the permanent MAC address by the following flag:
`SIOCETHTOOL` 

Is it possible for you to implement this function?
Thanks
