+.Sh NAME
+.Nm ixl
+.Nd "Intel XL710 Ethernet 40Gb Base driver"
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device ixl"
+.Ed
+.Pp
+To load the driver as a
+module at boot time, place the following lines in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+if_ixl_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for PCI Express adapters or LOMs
+in the XL710 Family of ethernet devices.
+The driver supports Jumbo Frames, TX/RX checksum offload,
+TCP segmentation offload (TSO), Large Receive Offload (LRO), VLAN
+tag insertion/extraction, VLAN checksum offload, VLAN TSO, and
+Receive Side Steering (RSS), all for both IPv4 and IPv6.
+For further hardware information and questions related to hardware
+requirements, see
+.Pa http://support.intel.com/ .
+.Pp
+Support for Jumbo Frames is provided via the interface MTU setting.
+Selecting an MTU larger than 1500 bytes with the
+.Xr ifconfig 8
+utility configures the adapter to receive and transmit Jumbo Frames.
+The maximum MTU size for Jumbo Frames is 9706.
+.Pp
+Offloads are also controlled via the interface, for instance,
+checksumming for both IPv4 and IPv6 can be set and unset, TSO4
+and/or TSO6, and finally LRO can be set and unset.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh HARDWARE
+The
+.Nm

+.El
+.Pp
+Note that X710/XL710 Based SFP+ adapters also support all passive and active
+limiting direct attach cables that comply with SFF-8431 v4.1 and
+SFF-8472 v10.4 specifications.
+.Sh LOADER TUNABLES
+Tunables can be set at the
+.Xr loader 8
+prompt before booting the kernel or stored in
+.Xr loader.conf 5 .
+.Bl -tag -width indent
+.It Va hw.ixl.enable_msix
+Allows one to enable/disable MSIX, thus forcing MSI instead.
+.It Va hw.ixl.ringsz
+Set the number of descriptors in the rings, note that this
+changes BOTH the TX and RX rings, they cannot be set independently.
+.It Va hw.ixl.max_queues
+Set the number of queues (each a TX/RX pair) for the port, this
+allows one to override the autocalculation if it is set to 0.
+.It Va hw.ixl.dynamic_rx_itr
+The dynamic RX interrupt control, set to 1 to enable.
+.It Va hw.ixl.dynamic_tx_itr
+The dynamic TX interrupt control, set to 1 to enable.
+.It Va hw.ixl.rx_itr
+The RX interrupt rate value, set to 8K by default.
+.It Va hw.ixl.tx_itr
+The TX interrupt rate value, set to 4K by default.
+.El
+.Sh SYSCTL PROCEDURES
+.Bl -tag -width indent
+.It Va hw.ixl.fc
+Allows one to set the flow control value.
+A value of 0 disables
+flow control, 3 enables full, 1 is RX, and 2 is TX pause.
+.It Va hw.ixl.advertise_speed
+Allows one to set advertised link speeds, this will then
+cause a link renegotiation.
+With the appropriate adapter
+this can cause a link at 10GB, 1GB, or 100MB.
+.It Va hw.ixl.current_speed
+This is a display of the current setting.
+.It Va hw.ixl.fw_version
+This is a display of the Firmware version.
+.El
+.Sh Interrupt Storms
+It is important to note that 40G operation can generate high
+numbers of interrupts, often incorrectly being interpreted as
+a storm condition in the kernel.
+It is suggested that this
+be resolved by setting:
+.Bl -tag -width indent
+.It Va hw.intr_storm_threshold: 0
+.El
