Add support LAN8720 ? #70

Greetings! First of all, thanks for your great work! This deserves great respect.

I would like to assemble a gateway based on ESP32 but using a wired LAN connection, - the boiler is installed in the basement, poor radio connection. Now there are many boards based on ESP32-WROOM (4 MB) with built-in LAN8720A (Ethernet PHY), there are even boards with POE. Only a small modification of the existing firmware is needed.

Perhaps you will be able to implement it? If suddenly you do not have time, but you are ready to accept help - I could, of course, under full non-disclosure terms, make this functionality possible.

for the time being I wouldn't include it as the effort is wuite high with little benefit coming from it (adapter with Ethernet exists already). Plus, for reliable quick Ethernet connection there is no need for this special low-latency firmware anyway

Hi john30,

Unfortunately W5500 provides no POE. As LAN8720 is rising with POE feature, it would be a huge improvement to ebus-esp project.

Please reconsider to include LAN8720 support.

Regards

you can use a simple adapter like this to extract power from PoE.
