If unspecified, the value can be overwritten via global defaults, see manual of NetworkManager.conf.

This property allows to specify that certain bits are fixed. Note that the least significant bit of the first MAC address will always be unset to create a unicast MAC address. If the property is NULL, it is eligible to be overwritten by a default connection setting.

The set bits of the mask are to be filled with the current MAC address of the device, while the unset bits are subject to randomization. Setting \"FE:FF:FF:00:00:00\" means to preserve the OUI of the current MAC address and only randomize the lower 3 bytes using the \"random\" or \"stable\" algorithm. If the value contains one additional MAC address after the mask, this address is used instead of the current MAC address to fill the bits that shall not be randomized. For example, a value of \"FE:FF:FF:00:00:00 68:F7:28:00:00:00\" will set the OUI of the MAC address to 68:F7:28, while the lower bits are randomized.
