Lenny Maiorani fd97f23cef MACAddress: Unit testing for basic functionality
Problem:
- There are no unit tests for `MACAddress` class. This makes it
  difficult to refactor and ensure the same behavior.
- `m_data` private member variable is uninitialized leading to undefined
  behavior of `is_zero()`.

Solution:
- Add unit tests to cover basic functionality.
- Initialize `m_data`.
