Subject: net: usb: cdc_ncm: add support  IFF_NOARP

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;
	...
}
