Packet aggregation is used to join multiple packets together into a single transmission unit. This helps reduce the overhead associated with each transmission. Packet aggregation should only be used when WAN devices have a very low Packet Per Second transmission rate.

Notes
- The feature is disabled by default
- The coalesce wait time is the maximum time in milliseconds to wait to construct a full packet.
