It's the same platform as PL-25A1 but with USB3.0 interface so basically I only added right vendor/device id to get detected. Maximum throughput I managed to get was about 1.5Gbps using iperf. I'll investigate usbnet to get even higher throughput, if you have any tips where to look, let me know. Developed and tested under 4.2.0-25.
