Ethernet

[fesch]

Applied patch to libtcpip_adapter to allow ETH to be used with a static configuration. (Pull request in ESP-IDF has been made but not integrated yet.)

Added a first version of an Ethernet library for LAN8720 based adapters as well a slightly modified copy of the ESP8266 WebServer (while waiting for a common repository for ESP8266 & ESP32).

Why mixing those two libs? Also too quick on the ethernet ;) I have most boards out there with the different chips and will actually need to implement them for all ;) I can not merge the web server only to remove it later ;) What boards did you test ethernet with?

[fesch]

• I originally headed for a WebServer but ended up with the need to first code the Ethernet library. Being asked by other users, I build both ...
• Of course Ethernet should be extended to fit other chips too, but as I only have the one with the LAN8720, I thought this would be a good beginning and wanted to share my code (as I was not able to find something working out-of-the-box on the net ...).
• I own an ESP32-EVB from Olimex.

Hi!
on olimex esp32-evb schematic is Lan8710,
the external LAN8720 is connected??

I have both olimex boards (big thanks to Olimex) and I also have another unreleased yet board based on the TK110. I will prep support for all and I'm thinking of not using Ethernet for that or maybe use it through defines so it would not interfere with the normal Ethernet classes for other SPI based LAN chips. I have code running for my 110 board and need to test the Olimex implementations and prepare board definitions for them. All under way :) IPv6 is also about to be merged for ETH

Hi!
This work with (ebay) waveshare LAN8720 module.
In ethernet.h modify #define ETH_PHY_ADDR PHY1 //waveshare
