Immediately configured via plug & play thanks to a matching Linux kernel at the start, short for Linux on DHCP and already liefs without problems. Throughput I can not test unfortunately, but it's definitely an improvement over the 100 Mbit interface because I could not take my camera recordings (FullHD 40 Mbit / s - about 50GB Bluray quality) not stream from the NAS, now it works.
