+.Sh NAME
+.Nm enic
+.Nd "VIC Ethernet NIC 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 iflib"
+.Cd "device enic"
+.Ed
+.Pp
+To load the driver as a module at run-time,
+run the following command as root:
+.Bd -literal -offset indent
+kldload if_enic
+.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_enic_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for Cisco Virtual Interface Card.
+Support is limited to basic network connectivity.
+Media is controlled by the NIC itself since there can be multiple
+virtual PCI NIC devices exposed to the PCI bus.
+.Sh HARDWARE
+The
+.Nm
+driver should supports all known Cisco VIC cards.
+.Sh CONFIGURATION
+The
+.Nm
+network interface is configured using
+.Xr ifconfig 8
+and the
+.Xr sysctl 8
+tree at
+.Dv dev.enic.<N> .
+All configurable entries are also tunables, and can be put directly into the
+.Xr loader.conf 5
+for persistent configuration.
+.Sh SEE ALSO
+.Xr ifconfig 8
+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Fx 14.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+driver was written by
+.An Cisco UCS team
+based of the DPDK driver.
