Name	Type	Description
Ipv4Encap	simple module	Handles IPv4 encapsulation and decapsulation for network emulation. Adds IPv4 headers to outgoing packets and removes them from incoming packets. Processes packet tags for fields like TOS, DSCP, ECN, and hop limit. Supports socket operations and manages protocol registration for dispatching packets to the appropriate upper layer protocols.
