Is the new ThinkPad Thunderbolt 3 Dock compatible with P50?
Dock details page (https://pcsupport.lenovo.com/cz/en/solutions/acc100356) only list P51s, but not P50. But P50 claims support for Thunderbold 3.
If yes, can I connect Ethernet LAN over the dock? And what driver I need to install?

If you want a ThinkPad that charges over its Thunderbolt 3/USB Type-C connector, you should look at one of the models like the P51s or P40 Yoga, which use a 65 Watt power supply.
If you want a ThinkPad which uses Intel Xeon CPUs, has four SO-DIMM modules for up to 64GB of RAM, multiple drive bays, etc., you'll need to purchase a model from the P50/P51 or P70/P71 series, and those use 170 or 230 watts, respectively.
Lenovo does a lot of cool stuff with power supplies, battery energy density, cooling systems and so forth, but, unfortunately, this is limitation of the USB Power Delivery specification itself. It's possible that the USB Implementers Forum will update the standard in the future, but that is a standard which has to be ratified by them; Lenovo just can't make a non-compatible device and still sell it as being Thunderbolt or USB compatible.
