arm64: dts: stratix10: fix multicast filtering

aakoskin · Dinh Nguyen · commit fd5ba6ee3187 · 2018-11-05T13:17:33.000-06:00
On Stratix 10, the EMAC has 256 hash buckets for multicast filtering. This needs to be specified in DTS, otherwise the stmmac driver defaults to 64 buckets and initializes the filter incorrectly. As a result, e.g. valid IPv6 multicast traffic ends up being dropped.
