Force docker container to use host machine MAC address

[Hudson86]

I am providing a docker container for my software that would run directly on user machine. The software is supposed to use Node locked license which would be bound to the MAC address of the host machine. FlexLM is used to validate the license.

The problem is that the docker container does not by default accesses the host machine's MAC address. One has to either bind the docker with host machine network using the --net argument or provide the MAC address explicitly using the --mac-address argument.

The problem is that one can pass any argument in --mac-address argument and the docker container will use that MAC address. This defeats the whole purpose of Node locked license. How do I make sure that the docker always gets the host machine's MAC address?
