This is an automatically generated commit which aids following Kernel patch history,
as git will see the move and copy as a rename thus defeating the purpose.

+ dpaa2_mac_is_type_phy()
+
+dpaa2_mac_is_type_fixed() is a header with no implementation and no
+callers, which is referenced from the documentation though. It can be
+deleted.
+
+On the other hand, it would be useful to reuse the code between
+dpaa2_eth_is_type_phy() and dpaa2_switch_port_is_type_phy(). That common
+code should be called dpaa2_mac_is_type_phy(), so let's create that.
+
+The removal and the addition are merged into the same patch because,
+in fact, is_type_phy() is the logical opposite of is_type_fixed().

+
+dpaa2_mac_disconnect() will only be called with a NULL mac->phylink if
+dpaa2_mac_connect() failed, or was never called.
+
+The callers are these:
+
+dpaa2_eth_disconnect_mac():

+priv->mac can be NULL, but in that case, dpaa2_eth_is_type_phy() returns
+false, and dpaa2_mac_disconnect() is never called. Similar for
+dpaa2-switch.
+
+When priv->mac is non-NULL, it means that dpaa2_mac_connect() returned
+zero (success), and therefore, priv->mac->phylink is also a valid

+Subject: [PATCH 07/14] net: dpaa2-eth: assign priv->mac after
+ dpaa2_mac_connect() call
+
+There are 2 requirements for correct code:
+
+- Any time the driver accesses the priv->mac pointer at runtime, it
+ either holds NULL to indicate a DPNI-DPNI connection (or unconnected
+ DPNI), or a struct dpaa2_mac whose phylink instance was fully
+ initialized (created and connected to the PHY). No changes are made to
+ priv->mac while it is being used. Currently, rtnl_lock() watches over
+ the call to dpaa2_eth_connect_mac(), so it serves the purpose of
+ serializing this with all readers of priv->mac.
+
+- dpaa2_mac_connect() should run unlocked, because inside it are 2
+ phylink calls with incompatible locking requirements: phylink_create()
+ requires that the rtnl_mutex isn't held, and phylink_fwnode_phy_connect()
+ requires that the rtnl_mutex is held. The only way to solve those
+ contradictory requirements is to let dpaa2_mac_connect() take
+ rtnl_lock() when it needs to.
+
+To solve both requirements, we need to identify the writer side of the
+priv->mac pointer, which can be wrapped in a mutex private to the driver
+in a future patch. The dpaa2_mac_connect() cannot be part of the writer
+side critical section, because of an AB/BA deadlock with rtnl_lock().
+
+So the strategy needs to be that where we prepare the DPMAC by calling
+dpaa2_mac_connect(), and only make priv->mac point to it once it's fully
+prepared. This ensures that the writer side critical section has the
+absolute minimum surface it can.
+
+The reverse strategy is adopted in the dpaa2_eth_disconnect_mac() code
+path. This makes sure that priv->mac is NULL when we start tearing down
+the DPMAC that we disconnected from, and concurrent code will simply not
+see it.
+
+No locking changes in this patch (concurrent code is still blocked by
+the rtnl_mutex).

+Subject: [PATCH 09/14] net: dpaa2: publish MAC stringset to ethtool -S even if
+ MAC is missing
+
+DPNIs and DPSW objects can connect and disconnect at runtime from DPMAC
+objects on the same fsl-mc bus. The DPMAC object also holds "ethtool -S"
+unstructured counters. Those counters are only shown for the entity
+owning the netdev (DPNI, DPSW) if it's connected to a DPMAC.
+
+The ethtool stringset code path is split into multiple callbacks, but
+currently, connecting and disconnecting the DPMAC takes the rtnl_lock().
+This blocks the entire ethtool code path from running, see
+ethnl_default_doit() -> rtnl_lock() -> ops->prepare_data() ->
+strset_prepare_data().
+
+This is going to be a problem if we are going to no longer require
+rtnl_lock() when connecting/disconnecting the DPMAC, because the DPMAC
+could appear between ops->get_sset_count() and ops->get_strings().
+If it appears out of the blue, we will provide a stringset into an array
+that was dimensioned thinking the DPMAC wouldn't be there => array
+accessed out of bounds.
+
+There isn't really a good way to work around that, and I don't want to
+put too much pressure on the ethtool framework by playing locking games.
+Just make the DPMAC counters be always available. They'll be zeroes if
+the DPNI or DPSW isn't connected to a DPMAC.

+Subject: [PATCH 11/14] net: dpaa2-eth: connect to MAC before requesting the
+ "endpoint changed" IRQ
+
+dpaa2_eth_connect_mac() is called both from dpaa2_eth_probe() and from
+dpni_irq0_handler_thread().
+
+It could happen that the DPNI gets connected to a DPMAC on the fsl-mc
+bus exactly during probe, as soon as the "endpoint change" interrupt is
+requested in dpaa2_eth_setup_irqs(). This will cause the
+dpni_irq0_handler_thread() to register a phylink instance for that DPMAC.
+
+Then, the probing function will also try to register a phylink instance
+for the same DPMAC, operation which should fail (and this will fail the
+probing of the driver).
+
+Reorder dpaa2_eth_setup_irqs() and dpaa2_eth_connect_mac(), such that
+dpni_irq0_handler_thread() never races with the DPMAC-related portion of
+the probing path.
+
+Also reorder dpaa2_eth_disconnect_mac() to be in the mirror position of
+dpaa2_eth_connect_mac() in the teardown path.

+Subject: [PATCH 12/14] net: dpaa2-eth: serialize changes to priv->mac with a
+ mutex
+
+The dpaa2 architecture permits dynamic connections between objects on
+the fsl-mc bus, specifically between a DPNI object (represented by a
+struct net_device) and a DPMAC object (represented by a struct phylink).
+
+The DPNI driver is notified when those connections are created/broken
+through the dpni_irq0_handler_thread() method. To ensure that ethtool
+operations, as well as netdev up/down operations serialize with the
+connection/disconnection of the DPNI with a DPMAC,
+dpni_irq0_handler_thread() takes the rtnl_lock() to block those other
+operations from taking place.
+
+There is code called by dpaa2_mac_connect() which wants to acquire the
+rtnl_mutex once again, see phylink_create() -> phylink_register_sfp() ->
+sfp_bus_add_upstream() -> rtnl_lock(). So the strategy doesn't quite
+work out, even though it's fairly simple.
+
+Create a different strategy, where all code paths in the dpaa2-eth
+driver access priv->mac only while they are holding priv->mac_lock.
+The phylink instance is not created or connected to the PHY under the
+priv->mac_lock, but only assigned to priv->mac then. This will eliminate
+the reliance on the rtnl_mutex.
+
+Add lockdep annotations and put comments where holding the lock is not
+necessary, and priv->mac can be dereferenced freely.

+
+The dpaa2-switch driver uses a DPMAC in the same way as the dpaa2-eth
+driver, so we need to duplicate the locking solution established by the
+previous change to the switch driver as well.

+Subject: [PATCH 14/14] net: dpaa2-mac: move rtnl_lock() only around
+ phylink_{,dis}connect_phy()
+
+After the introduction of a private mac_lock that serializes access to
+priv->mac (and port_priv->mac in the switch), the only remaining purpose
+of rtnl_lock() is to satisfy the locking requirements of
+phylink_fwnode_phy_connect() and phylink_disconnect_phy().
+
+But the functions these live in, dpaa2_mac_connect() and
+dpaa2_mac_disconnect(), have contradictory locking requirements.
+While phylink_fwnode_phy_connect() wants rtnl_lock() to be held,
+phylink_create() wants it to not be held.
+
+Move the rtnl_lock() from top-level (in the dpaa2-eth and dpaa2-switch
+drivers) to only surround the phylink calls that require it, in the
+dpaa2-mac library code.
+
+This is possible because dpaa2_mac_connect() and dpaa2_mac_disconnect()
+run unlocked, and there isn't any danger of an AB/BA deadlock between
+the rtnl_mutex and other private locks.
