## Mapping PCIe devices to fm10k driver
* It is always a good idea to set up IOMMU in your kernel cmdline GRUB_CMDLINE_LINUX_DEFAULT `intel_iommu=on iommu=pt`.
* (optional) Probably you also want hugepages! DPDK and similar want them badly.
* Use `# lshw -c network -businfo` to find the PCIe bus of the given devices.
* Use `# lshw -c network -businfo` to find the PCIe bus of the given devices. (_Ethernet Switch FM10000 Host Interface_)
* Two devices should appear per card. Make sure the slot they are connected to have 16x PCIe lanes and your BIOS is setup to do 8x8 PCIe bifurcation.
* Only the main card is needed directly to be able to control the switch.
* Map it permanently using for example `# driverctl set-override 0000:01:00.0 fm10k` for listed device `pci@0000:01:00.0`.
* If needed, `# rmmod fm10k` and `# modprobe fm10k` to reload the module.
* A restart might be needed to properly load UIO
* A restart might also be needed to properly load UIO (`/dev/uio0`).
## Running rdif
* See `src/rdif/readme.txt` once available.
