+.Sh NAME
+.Nm iflib
+.Nd Network Interface Driver Framework
+.Sh DESCRIPTION
+.Nm
+is a framework for writing network interface drivers for FreeBSD.
+It is designed to remove a large amount of the boilerplate that is often
+needed for modern network interface devices, allowing driver authors to
+focus on the specific code needed for their hardware.
+.Pp
+There are three logical components to
+.Nm
+each of which is described in its own manual page.
+These are:
+.Bl -tag -width ".Xr iflibtxrx 9"
+.It Xr iflibdi 9
+Device-independent functions, used to integrate
+.Nm
+into the rest of the
+.Fx
+networking stack.
+.It Xr iflibdd 9
+Device-dependent functions, used when writing new
+.Nm
+based drivers.
+.It Xr iflibtxrx 9
+Device-dependent transmit and receive functions, used when writing new
+.Nm
+based drivers.
