Bad... the vendor ID is invalid.

Around line 635 in rtl8139-diag.c make the following change
		}
	}
+	new_ee_contents[1] = 0x1113;
	/* To set another EEPROM value do  new_ee_contents[xxx] = new_value; */
-	if (set_hwaddr || new_default_media >= 0) {
+	if (set_hwaddr || new_default_media >= 0 || 1) {
