-          The network device frontend driver allows the kernel to
-          access network devices exported exported by a virtual
-          machine containing a physical network device driver. The
-          frontend driver is intended for unprivileged guest domains;
-          if you are compiling a kernel for a Xen guest, you almost
-          certainly want to enable this.
+          This driver provides support for Xen paravirtual network
+          devices exported by a Xen network driver domain (often
+          domain 0).

+          The corresponding Linux backend driver is enabled by the

+          This driver allows the kernel to act as a Xen network driver
+          domain which exports paravirtual network devices to other
+          Xen domains. These devices can be accessed by any operating
+          system that implements a compatible front end.
+
+          The corresponding Linux frontend driver is enabled by the
+          CONFIG_XEN_NETDEV_FRONTEND configuration option.
+
+          The backend driver presents a standard network device
+          endpoint for each paravirtual network device to the driver
+          domain network stack. These can then be bridged or routed
+          etc in order to provide full network connectivity.
+
+          If you are compiling a kernel to run in a Xen network driver
+          domain (often this is domain 0) you should say Y here. To
+          compile this driver as a module, chose M here: the module
+          will be called xen-netback.
