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
This also makes it possible for Communication to create more instances of Packetizer
This is necessary because Packetizer is not thread safe,
so when we support more VNETs we will need to create more Packetizers.
