RDMA

The Linux Plumbers 2017 RDMA mini-conference track continues tradition established in 2016, where we discussed different range of topics, starting from kernel core (integration into netdev, new fabrics, …) through kernel ABI changes upto userspace libraries.

That mini-conference was extremely fruitful with a lot of code proposed and merged afterwards.
