Subject: [RFC PATCH net-next 08/11] net: dsa: microchip: lan937x: avoid mib read for cascaded port
Date: Thu, 2 Feb 2023 18:29:27 +0530	[thread overview]
Message-ID: <20230202125930.271740-9-rakesh.sankaranarayanan@microchip.com> (raw)
In-Reply-To: <20230202125930.271740-1-rakesh.sankaranarayanan@microchip.com>

Cascaded port need not be involved in mib read process. Unlike cpu port,
mib read function will be called for all other ports. Add check to skip
function if port is of type DSA_PORT_TYPE_DSA.
