Subject: [PATCH v2 2/6] net: dsa: enable promiscuous mode for switch master edev
Date: Thu,  3 Nov 2022 14:13:47 +0100	[thread overview]
Message-ID: <20221103131351.2059683-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20221103131351.2059683-1-o.rempel@pengutronix.de>

Typical use case for DSA framework on barebox a port multiplexer. This
means, we mostly have different MAC addresses on each port. To make this
work, we need to enable promiscuous mode on the master Ethernet
controller.

With this patch, promiscuous mode will be enabled automatically, as soon
as at least one switch port is enabled and this mode will be disabled
after all switch ports are disabled as well.
