From 7932d53162dc6550fc56b013da32c0975784647c Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sat, 9 Oct 2021 15:27:36 +0300 Subject: [PATCH] dt-bindings: net: dsa: document felix family in dsa-tag-protocol The Vitesse/Microsemi/Microchip family of switches supported by the Felix DSA driver is capable of selecting between the native tagging protocol and ocelot-8021q. This is necessary to enable flow control on the CPU port. Certain systems where these switches are integrated use the switch as a port multiplexer, so the termination throughput is paramount. Changing the tagging protocol at runtime is possible for these systems, but since it is known beforehand that one tagging protocol will provide strictly better performance than the other, just allow them to specify the preference in the device tree.
