This pair of patches are the result of discovering a failure to correctly receive IPv6 multicast packets on such a device (in particular DHCPv6 requests and RA solicitations). Putting the device into promiscuous mode, or allmulti, both resulted in such packets correctly being received. Examination of the vendor driver (nss-gmac from the qsdk) shows that it does not enable the multicast filter and instead falls back to allmulti. Extend the base dwmac1000 driver to fall back when there's no suitable hardware filter, and update the ipq806x platform to request this.
