[PATCH] zd1211rw: Support for multicast addresses

Support for multicast adresses is implemented by supporting the
set_multicast_list() function of the network device. Address
filtering is supported by a group hash table in the device.

This is based on earlier work by Benoit Papillaut. Fixes multicast packet
reception and ipv6 connectivity:
