Networking Layer upgrades

Networking Layer Upgrades encompass improvements and changes to the components that facilitate communication and data exchange within the Ethereum network. These upgrades include the discovery stack and the devp2p stack. The discovery stack ensures efficient peer discovery, enabling nodes to find and connect with each other. The devp2p stack provides the protocols for peer-to-peer communication, ensuring robust and secure data transmission across the network.
