-# RDMA (ibverb) Ethernet driver {#rdma_doc}
-
-This driver relies on Linux rdma-core (libibverb) userspace poll-mode driver
-to rx/tx Ethernet packets. Despite using the RDMA APIs, this is **not** about
-RDMA (no Infiniband, no RoCE, no iWARP), just pure traditional Ethernet
-packets.
-
-## Maturity level
-Under development: it should work, but has not been thoroughly tested.
-
-## Supported Hardware
- - Mellanox ConnectX-4
- - Mellanox ConnectX-5
-
-## Features
- - bifurcation: MAC based flow steering for transparent sharing of a single
-physical port between multiple virtual interfaces including Linux netdev
- - multiqueue
-
-## Security considerations
-When creating a rdma interface, it will receive all packets to the MAC address
-attributed to the interface plus a copy of all broadcast and multicast
-traffic.
-The MAC address is under the control of VPP: **the user controlling VPP can
-divert all traffic of any MAC address to the VPP process, including the Linux
-netdev MAC address as long as it can create a rdma interface**.
-The rights to create a rdma interface are controlled by the access rights of
-the `/dev/infiniband/uverbs[0-9]+`device nodes.
-
-## Quickstart
-1. Make sure the `ib_uverbs` module is loaded:
-```
-~# modprobe ib_uverbs
-```
-2. In VPP, create a new rdma virtual interface tied to the Linux netdev of the
-physical port you want to use (`enp94s0f0` in this example):
-```
-vpp# create int rdma host-if enp94s0f0 name rdma-0
-```
-3. Use the interface as usual, eg.:
-```
-vpp# set int ip addr rdma-0 1.1.1.1/24
-vpp# set int st rdma-0 up
-vpp# ping 1.1.1.100`
-```
-
-## Containers support
-It should work in containers as long as:
- - the `ib_uverbs` module is loaded
- - the device nodes `/dev/infiniband/uverbs[0-9]+` are usable from the
- container (but see [security considerations](#Security considerations))
-
-## SR-IOV VFs support
-It should work on SR-IOV VFs the same way it does with PFs. Because of VFs
-security containment features, make sure the MAC address of the rdma VPP
-interface matches the MAC address assigned to the underlying VF.
-For example:
-```
-host# echo 1 > /sys/class/infiniband/mlx5_0/device/sriov_numvfs
-host# ip l set dev enp94s0f0 vf 0 mac 92:5d:f5:df:b1:6f spoof on trust off
-host# ip l set dev enp94s0f2 up
-vpp# create int rdma host-if enp94s0f2 name rdma-0
-vpp# set int mac address rdma-0 92:5d:f5:df:b1:6f
-```
-If you plan to use L2 features such as switching, make sure the underlying
-VF is configured in trusted mode and spoof-checking is disabled (of course, be
-aware of the [security considerations](#Security considerations)):
-```
-host# ip l set dev enp94s0f0 vf 0 spoof off trust on
-```
-
-## Direct Verb mode
-Direct Verb allows the driver to access the NIC HW RX/TX rings directly
-instead of having to go through libibverb and suffering associated overhead.
-It will be automatically selected if the adapter supports it.
