r8152: allow userland to disable multicast
The rtl8152 driver does not disable multicasting when userspace asks
it to. For example:
$ ifconfig eth0 -multicast -allmulti
$ tcpdump -p -i eth0 # will still capture multicast frames
Fix by clearing the device multicast filter table when multicast and
allmulti are both unset.
Tested as follows:
- Set multicast on eth0 network interface
- verify that multicast packets are coming in:
$ tcpdump -p -i eth0
- Clear multicast and allmulti on eth0 network interface
- verify that no more multicast packets are coming in:
$ tcpdump -p -i eth0
