+Configure Device
+================
+
+This section explains how to use Agilio SmartNICs running basic NIC firmware.
+
+Configure interface link-speed
+------------------------------
+The following steps explains how to change between 10G mode and 25G mode on
+Agilio CX 2x25GbE cards. The changing of port speed must be done in order,
+port 0 (p0) must be set to 10G before port 1 (p1) may be set to 10G.
+
+Down the respective interface(s)::
+
+  $ ip link set dev <netdev port 0> down
+  $ ip link set dev <netdev port 1> down
+
+Set interface link-speed to 10G::
+
+  $ ethtool -s <netdev port 0> speed 10000
+  $ ethtool -s <netdev port 1> speed 10000
+
+Set interface link-speed to 25G::
+
+  $ ethtool -s <netdev port 0> speed 25000
+  $ ethtool -s <netdev port 1> speed 25000
+
+Reload driver for changes to take effect::
+
+  $ rmmod nfp; modprobe nfp
+
+Configure interface Maximum Transmission Unit (MTU)
+---------------------------------------------------
+
+The MTU of interfaces can temporarily be set using the iproute2, ip link or
+ifconfig tools. Note that this change will not persist. Setting this via
+Network Manager, or another appropriate OS configuration tool, is
+recommended as changes to the MTU using Network Manager can be made to
+persist.
+
+Set interface MTU to 9000 bytes::
+
+  $ ip link set dev <netdev port> mtu 9000
+
+It is the responsibility of the user or the orchestration layer to set
+appropriate MTU values when handling jumbo frames or utilizing tunnels. For
+example, if packets sent from a VM are to be encapsulated on the card and
+egress a physical port, then the MTU of the VF should be set to lower than
+that of the physical port to account for the extra bytes added by the
+additional header. If a setup is expected to see fallback traffic between
+the SmartNIC and the kernel then the user should also ensure that the PF MTU
+is appropriately set to avoid unexpected drops on this path.
+
+Configure Forward Error Correction (FEC) modes
+----------------------------------------------
+
+Agilio SmartNICs support FEC mode configuration, e.g. Auto, Firecode Base-R,
+ReedSolomon and Off modes. Each physical port's FEC mode can be set
+independently using ethtool. The supported FEC modes for an interface can
+be viewed using::
+
+  $ ethtool <netdev>
+
+The currently configured FEC mode can be viewed using::
+
+  $ ethtool --show-fec <netdev>
+
+To force the FEC mode for a particular port, auto-negotiation must be disabled
+(see the `Auto-negotiation`_ section). An example of how to set the FEC mode
+to Reed-Solomon is::
+
+  $ ethtool --set-fec <netdev> encoding rs
+
+Auto-negotiation
+----------------
+
+To change auto-negotiation settings, the link must first be put down. After the
+link is down, auto-negotiation can be enabled or disabled using::
+
+  ethtool -s <netdev> autoneg <on|off>
+
