Motivation: Netty uses epoll edge-triggered by default forever and there is really not reason why someone should use level-triggered (its considered a implementation detail). Modifications: - Remove code that was related to level-triggered mode - Adjust testclass names Result: Fixes https://github.com/netty/netty/issues/9349
