           This adds a specialized tap character device driver that is based
           on the MAC-VLAN network interface, called macvtap. A macvtap device
           can be added in the same way as a macvlan device, using 'type

+          device based on the CoreChip-sz SR9800 chip.
+
+          This driver makes the adapter appear as a normal Ethernet interface,
+          typically on eth0, if it is the only ethernet device, or perhaps on
+          eth1, if you have a PCI or ISA ethernet card installed.
+
+          To compile this driver as a module, choose M here: the
+          module will be called sr9800.
