net: ethernet: stmmac: Disable hardware multicast filter
The IPQ806x does not appear to have a functional multicast ethernet address filter. This was observed as a failure to correctly receive IPv6 packets on a LAN to the all stations address. Checking the vendor driver shows that it does not attempt to enable the multicast filter and instead falls back to receiving all multicast packets, internally setting ALLMULTI. Use the new fallback support in the dwmac1000 driver to correctly achieve the same with the mainline IPQ806x driver. Confirmed to fix IPv6 functionality on an RB3011 router.
