Hi Alexey, Recently I met a Modem which cannot do ARP. But I found our cdc_ncm_bind() function cannot handle this special case. Do you have any plan to handle it? static int cdc_ncm_bind(struct usbnet *dev, struct usb_interface *intf) { ... /* cannot do ARP */ dev->net->flags |= IFF_NOARP; ... } -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
