sfc: Insert multicast filters as well as mismatch filters in promiscuous mode
If a function is in promiscuous mode and another function has a broadcast or multicast filter inserted, the function in promiscuous mode won't see that broadcast or multicast traffic. Most notably this breaks broadcast, which means ARP doesn't work. Less show-stoppingly, a function listening on a multicast address that's also in promiscuous mode will not see that multicast traffic if another function is also listening on that multicast address.
