As far as I know there are none. First there are only a few poker sites that allow you to play with crypto, and they aren't very good either, because they have a small player base. If you restrict your search even further (like finding poker sites with ether), you will probably never play poker with crytpo.
I don't think gambling with ether will be very popular because that is not the main purpose of that coin as well, since Ether is supposed to be a platform to run smart contracts, so it's niche will be having new crypto start ups emerging, that will use ether to raise capital for their projects (though ICOs).
