    Subject[PATCH v2] arm64: dts: stratix10: fix multicast filtering
    Date
    From: Aaro Koskinen <aaro.koskinen+linux@nokia.com>

    From: Aaro Koskinen <aaro.koskinen@nokia.com>

    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.

    Fixes: 78cd6a9d8e15 ("arm64: dts: Add base stratix 10 dtsi")
