This allows us to better implement alternative drivers
for devices, such as for device sharing servers or
talking to CoreMini processors within the same device.
The following fixups were added during the squash/merge:
Fix formatting in EthPhyMessage and EthPhyRegPacket
Device: Use std::make_shared when creating the EthPHYControl filter
Network: Create NetID String for EthPHYControl
EthPhyRegPacket: Constants in PascalCase
