@erj are you going to commit this once you've made the IXL updates required for it to function?

Yeah, that's the plan. If @bartosz.sobczak_intel.com is okay with the current version.

This will collide with the the projects/bsd_rdma_4_9 branch. Have you looked at that?

This doesn't appear to be connected to the kernel build via sys/conf/files. It also does not have a kernel config option via sys/conf/options.
