Subject: [PATCH] net: cdc_ncm: hook into set_rx_mode to admit multicast
traffic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
