Merge branch 'usbnet-multicast-filter-support-for-cdc-ncm-devices' 

Bjørn Mork says:

====================
usbnet: multicast filter support for cdc ncm devices

This revives a 2 year old patch set from Miguel Rodríguez
Pérez, which appears to have been lost somewhere along the
way.  I've based it on the last version I found (v4), and
added one patch which I believe must have been missing in
the original.

I kept Oliver's ack on one of the patches, since both the patch and
the motivation still is the same.  Hope this is OK..

Thanks to the anonymous user <wxcafe@wxcafe.net> for bringing up this
problem in https://bugs.debian.org/965074

This is only build and load tested by me.  I don't have any device
where I can test the actual functionality.
