[PATCH] net: cdc_ncm: USB_NET_CDC_NCM selects USB_NET_CDCETHER

[trix]

From: Tom Rix <trix@xxxxxxxxxx>

A link error

ld: drivers/net/usb/cdc_ncm.o:
  undefined reference to `usbnet_cdc_update_filter'

usbnet_cdc_update_filter is defined in cdc_ether.c
Building of cdc_ether.o is controlled by USB_NET_CDCETHER

Building of cdc_ncm.o is controlled by USB_NET_CDC_NCM

So add a select USB_NET_CDCETHER to USB_NET_CDC_NCM
