Subject: [PATCH v2 5/5] net: designware: eqos: do not receive pause frames
Date: Mon, 14 Aug 2023 07:32:29 +0200 [thread overview]
Message-ID: <20230814053229.2311097-6-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20230814053229.2311097-1-o.rempel@pengutronix.de>
Normally we need to care only about packets with not local MAC address
destination. It is needed to support HW setups with multiple MAC
addresses forwarded over one MAC. For example systems using DSA switch
as port multiplexer. In this case one single MAC should handle packets
with different MAC address destinations.
This functionality is provided by the EQOS_MAC_PACKET_FILTER_PR.
EQOS_MAC_PACKET_FILTER_PCF on other hand allow to capture ethernet
control frames like pause frames which are not handled by barebox.
