Subject: [PATCH v2] arm64: dts: stratix10: fix multicast filtering

From: Aaro Koskinen <[email protected]>

From: Aaro Koskinen <[email protected]>

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")

Hi,

This is the correct one, but unfortunately both git-send-email and
my SMTP server are trying to be too clever and prevents me sending
the patch in correct format. :-(
