Detailed Description

Layer 3 (Network) — IP routing and packet forwarding.

On ESP32 the network layer is fully managed by the lwIP TCP/IP stack. IP address assignment (DHCP or static), routing, and ICMP are all transparent to this library. This header exists as an architectural placeholder and extension point.

The current implementation is a no-op stub.

init_network_layer()

void init_network_layer

(

)

Initialise the network layer.

Currently a no-op; lwIP manages IP routing internally. Call this if you later add static-route configuration, ICMP echo handling, or custom network-layer diagnostics.
