I'm using some very cheap (~$200) ex-Alibaba FPGA boards for the initial development of the next-generation version. They have 8 lanes of PCIe gen 3 and two SFP28 capable of operation at 25 Gbps. Honestly that's pretty hard to beat. Support for other boards will be added in the near future. The new library will also include a new IP stack called Zircon, which supports UDP, among other things.
