Subject: [PATCH v5 net-next 5/5] net: cdc_ncm: hook into set_rx_mode to admit multicast traffic

From: Miguel Rodríguez Pérez <miguel@....uvigo.gal>

We set set_rx_mode to usbnet_cdc_update_filter provided
by cdc_ether that simply admits all multicast traffic
if there is more than one multicast filter configured.
