USB ethernet host driver bug fix/minor improvement

[David Smith <dsmith at redhat dot com>]

2002-07-26  David Smith  <dsmith@redhat.com>

	* host/ecos_usbeth.c (ecos_usbeth_probe):
	Two changes to the code that checks to see if this is the correct
	driver for the USB peripheral that was just loaded.  Fixed a bug
	that was comparing the product id of the peripheral to the vendor
	id.  Supports multiple implementations (vendor id/product id sets)
	so that the same driver could be used for several devices.
