Miller" <davem@...emloft.net>, Rob Herring <robh+dt@...nel.org> CC: Peter Ujfalusi <peter.ujfalusi@...com>, Sekhar Nori <nsekhar@...com>, <linux-kernel@...r.kernel.org>, Grygorii Strashko <grygorii.strashko@...com> Subject: [PATCH net-next 2/9] net: ethernet: ti: ale: add support for mac-only mode The new CPSW ALE version, available on TI K3 AM654/J721E SoCs family, allows to switch any external port to MAC only mode. When MAC only mode enabled this port be treated like a MAC port for the host. All traffic received is only sent to the host. The host must direct traffic to this port as the lookup engine will not send traffic to the ports with the p0_maconly bit set and the p0_no_learn also set. If p0_maconly bit is set and the p0_no_learn is not set, the host can send non-directed packets that can be sent to the destination of a MacOnly port. It is also possible that The host can broadcast to all ports including MacOnly ports in this mode. This patch add ALE supprt for MAC only mode.
