Re: [PATCH v4 3/4] Add .ndo_set_rx_mode to cdc_ncm_netdev_ops

This is another alternative, but it would require exporting
usbnet_set_rx_mode. The main drawback of this approach is that it would
need to make use that net_device_ops copy in cdc_ncm remains updated,
should usbnet.c version change.
On the other hand, the structure can be kept const.

Which alternative do you think is best?

The cdc_ncm driver overrides the net_device_ops structure used by usbnet
to be able to hook into .ndo_change_mtu. However, the structure was
missing the .ndo_set_rx_mode field, preventing the driver from
hooking into usbnet's set_rx_mode. This patch adds the missing callback to
usbnet_set_rx_mode in net_device_ops.
