Introduce fwnode_mdiobus_register_phy() to register PHYs on the mdiobus. From the compatible string, identify whether the PHY is c45 and based on this create a PHY device instance which is registered on the mdiobus. Along with fwnode_mdiobus_register_phy() also introduce fwnode_find_mii_timestamper() and fwnode_mdiobus_phy_device_register() since they are needed. While at it, also use the newly introduced fwnode operation in of_mdiobus_phy_device_register(). Signed-off-by:

The commit 8532f613 ("net: stmmac: introduce MSI Interrupt routines for mac, safety, RX & TX") introduced the converity warnings:- 1. Unused value (UNUSED_VALUE) assigned_value: Assigning value REQ_IRQ_ERR_MAC to irq_err here, but that stored value is not used. 2. Unused value (UNUSED_VALUE) assigned_value: Assigning value REQ_IRQ_ERR_NO to irq_err here, but that stored value is overwritten before it can used. 3. Unused value (UNUSED_VALUE) assigned_value: Assigning value REQ_IRQ_ERR_WOL to irq_err here, but that stored value is not used. Fixed these by removing the unnecessary value assignments.

It has been reported that on RTL8106e the link-up interrupt may be significantly delayed if the user enables ASPM L1. Per default ASPM is disabled. The change leaves L1 enabled on the PCIe link (thus still allowing to reach higher package power saving states), but the NIC won't actively trigger it. Reported-by:

Julian Wiedmann says: ==================== s390/qeth: updates 2021-06-11 please apply the following patch series for qeth to netdev's net-next tree. This enables TX NAPI for those devices that didn't use it previously, so that we can eventually rip out the qdio layer's internal interrupt machinery. Other than that it's just the normal mix of minor improvements and cleanups. ==================== Signed-off-by: -

Without the SWITCHDEV module, the bridgeport attribute LEARNING_SYNC of the physical device (self) does not provide any functionality. Instead of calling the no-op stub version of the switchdev functions, fail the setting of the attribute with an appropriate message. While at it, also add an error message for the 'not supported by HW' case. Signed-off-by:

qeth_tx_complete_buf() is the only remaining user of buf->q, and the callers can easily provide this as a parameter instead. Signed-off-by:

Julian Wiedmann authored
Maintaining a pointer inside the aob's user-definable area is fragile and unnecessary. At this stage we only need it to overload the buffer's state field, and to access the buffer's TX queue. The first part is easily solved by tracking the aob's state within the aob itself. This also feels much cleaner and self-contained. For enabling the access to the associated TX queue, we can store the queue's index in the aob. Signed-off-by:

With commit 396c1004 ("s390/qdio: let driver manage the QAOB") a pending TX buffer now has access to its associated QAOB during TX completion processing. We can thus reduce the amount of work & state propagation that needs to be done by qeth_qdio_handle_aob(). Move all this logic into the respective TX completion paths. Doing so even allows us to determine more precise TX_NOTIFY_* values via qeth_compute_cq_notification(aob->aorc, ...). Signed-off-by:

We have one field to track _whether_ a cmd is active on a ccw device ('irq_pending'), and one to track _which_ cmd it is ('active_cmd'). Get rid of the irq_pending field, by testing active_cmd for NULL. Signed-off-by: -

Set scan_threshold = 0 to opt out from the qdio layer's internal tasklet & timer mechanism for TX completions, and replace it with the TX NAPI infrastructure that qeth already uses for IQD devices. This avoids the fragile logic in qdio_check_output_queue(), enables tighter integration and gives us more tuning options via ethtool in the future. For now we continue to apply the same policy as the qdio layer: scan for completions if 32 TX buffers are in use, or after 1 sec. A re-scan is done after 10 sec, but only if no TX interrupt is pending. With scan_threshold = 0 we no longer get TX completion scans from within qdio_get_next_buffers(). So trigger these manually in qeth_poll() and in the RX path switch to the equivalent qdio_inspect_queue(). Signed-off-by:

While the qdio layer already tracks the number of HW interrupts for a device, there's value in understanding how many of them have been raised due to our TX completion logic. Signed-off-by:

Vladimir Oltean says: ==================== DSA tagging driver for NXP SJA1110 This series adds support for tagging data and control packets on the new NXP SJA1110 switch (supported by the sja1105 driver). Up to this point it used the sja1105 driver, which allowed it to send data packets, but not PDUs as those required by STP and PTP. To accommodate this new tagger which has both a header and a trailer, we need to refactor the entire DSA tagging scheme, to replace the "overhead" concept with separate "needed_headroom" and "needed_tailroom" concepts, so that SJA1110 can declare its need for both. There is also some consolidation work for the receive path of tag_8021q and its callers (sja1105 and ocelot-8021q). Changes in v3: Rebase in front of the "Port the SJA1105 DSA driver to XPCS" series which seems to have stalled for now. Changes in v2: Export the dsa_8021q_rcv and sja1110_process_meta_tstamp symbols to avoid build errors as modules. ==================== Signed-off-by:
