300 Say Y if you want to use one of the following 100Mbps USB Ethernet
301 device based on the CoreChip-sz SR9800 chip.
302
303 This driver makes the adapter appear as a normal Ethernet interface,
304 typically on eth0, if it is the only ethernet device, or perhaps on
305 eth1, if you have a PCI or ISA ethernet card installed.
306
307 To compile this driver as a module, choose M here: the
308 module will be called sr9800.
