Subject: [PATCH v3 net-next 14/15] net: dsa: felix: use promisc on master for PTP with tag_8021q
Date: Mon, 18 Jan 2021 18:17:30 +0200 [thread overview]
Message-ID: <20210118161731.2837700-15-olteanv@gmail.com> (raw)
In-Reply-To: <20210118161731.2837700-1-olteanv@gmail.com>
From: Vladimir Oltean <vladimir.oltean@nxp.com>
This is for the "no extraction IRQ" workaround, where the DSA master on
LS1028A (enetc) serves as a de-facto irqchip.
It needs to be promiscuous so that it will never drop a PTP frame (sent
to the 01-80-c2-00-00-0e multicast MAC address), otherwise the tagger
will get confused about which Ethernet PTP frame corresponds to which
PTP frame over the MMIO registers.
