Subject: [PATCH v1 net-next 4/6] net: dsa: ocelot: felix: add per-device-per-port quirks
Date: Fri, 19 Nov 2021 14:43:11 -0800	[thread overview]
Message-ID: <20211119224313.2803941-5-colin.foster@in-advantage.com> (raw)
In-Reply-To: <20211119224313.2803941-1-colin.foster@in-advantage.com>

Initial Felix-driver products (VSC9959 and VSC9953) both had quirks
where the PCS was in charge of rate adaptation. In the case of the
VSC7512 there is a differnce in that some ports (ports 0-3) don't have
a PCS and others might have different quirks based on how they are
configured.

This adds a generic method by which any port can have any quirks that
are handled by each device's driver.
