Subject: [PATCH net 0/3] cdc-ether: handle promiscuous mode

Hi,

Since kernel 3.16, my Lenovo USB network adapters (RTL8153) using
cdc-ether are not working anymore in a bridge.

This is due to commit c472ab68ad67db23c9907a27649b7dc0899b61f9, which
resets the packet filter when the device is bound.

The default packet filter set by cdc-ether does not include
promiscuous, while the adapter seemed to have promiscuous enabled by
default.

This patch series allows to support promiscuous mode for cdc-ether, by
hooking into set_rx_mode.

Incidentally, maybe this device should be handled by the r8152 driver,
but this patch series is still nice for other adapters.

Thanks

Olivier Blin (3):
  usbnet: add a callback for set_rx_mode
  cdc-ether: extract usbnet_cdc_update_filter function
  cdc-ether: handle promiscuous mode with a set_rx_mode callback
