See the [`smoltcp`](https://github.com/smoltcp-rs/smoltcp) README for a detailed list of implemented and
unimplemented features of the network protocols.

## Scope

Embassy-net aims to provide an equivalent to an OS network stack, which includes a DHCP client, TCP, UDP, ICMP, and
other OS sockets, and VLAN support. Higher-level protocols such as HTTP, and DHCP server are out of scope for this
project. For implementations of these protocols, see [`edge-net`](https://crates.io/crates/edge-net). See
[`nstpc`](https://crates.io/crates/sntpc) for an ntp client.

## PTP

Packet-time protocol support is partially in scope for this project; specifically providing timestamps for UDP and raw
socket ethernet requests. Clock calibration and other functions are not in-scope for this project and should be implemented
with another trait.

Implementation of this protocol is ongoing.

## Hardware support

- [`esp-wifi`](https://github.com/esp-rs/esp-wifi) for WiFi support on bare-metal ESP32 chips. Maintained by Espressif.
