Niklas Söderlund says: ==================== net: phy: marvell-88q2xxx: Enable auto negotiation for mv88q2110 This series enables auto negotiation for the mv88q2110 device. Previously this feature have been disabled for mv88q2110, while enabled for other devices supported by this driver. The initial driver implementation states this is due to the configuration sequence provided by the vendor did not work. By comparing the initialization sequence of other devices this driver supports and the out-of-tree PHY driver for mv88q2110 found in the Renesas BSP [1] I was able to figure out a working configuration. As I have no access to the datasheets of either of these devices it would be super if someone who has could sanity check the initialization sequence. With this series I'm able to auto negotiate both 1000Mbps and 100Mbps links without issue. # ethtool eth0 Settings for eth0: Supported ports: [ ] Supported link modes: 100baseT1/Full 1000baseT1/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 100baseT1/Full 1000baseT1/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Link partner advertised link modes: 100baseT1/Full 1000baseT1/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Link partner advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Auto-negotiation: on master-slave cfg: preferred master master-slave status: slave Port: Twisted Pair PHYAD: 0 Transceiver: external MDI-X: Unknown Link detected: yes SQI: 15/15 And the performance is good too.

2024-10-08net: phy: marvell-88q2xxx: Enable auto negotiation for mv88q2110Niklas Söderlund
The initial marvell-88q2xxx driver only supported the Marvell 88Q2110 PHY without auto negotiation support. The reason documented states that the provided initialization sequence did not to work. Now a method to enable auto negotiation have been found by comparing the initialization of other supported devices and an out-of-tree PHY driver. Perform the minimal needed initialization of the PHY to get auto negotiation working and remove the limitation that disables the auto negotiation feature for the mv88q2110 device. With this change a 1000Mbps full duplex link is able to be negotiated between two mv88q2110 and the link works perfectly. The other side also reflects the manually configure settings of the master device. # ethtool eth0 Settings for eth0: Supported ports: [ ] Supported link modes: 100baseT1/Full 1000baseT1/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 100baseT1/Full 1000baseT1/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Link partner advertised link modes: 100baseT1/Full 1000baseT1/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Link partner advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Auto-negotiation: on master-slave cfg: preferred master master-slave status: slave Port: Twisted Pair PHYAD: 0 Transceiver: external MDI-X: Unknown Link detected: yes SQI: 15/15 Before this change I was not able to manually configure 1000Mbps link, only a 100Mpps link so this change providers an improvement in performance for this device.

2024-10-08net: phy: aquantia: allow forcing order of MDI pairsDaniel Golle
Despite supporting Auto MDI-X, it looks like Aquantia only supports swapping pair (1,2) with pair (3,6) like it used to be for MDI-X on 100MBit/s networks. When all 4 pairs are in use (for 1000MBit/s or faster) the link does not come up with pair order is not configured correctly, either using MDI_CFG pin or using the "PMA Receive Reserved Vendor Provisioning 1" register. Normally, the order of MDI pairs being either ABCD or DCBA is configured by pulling the MDI_CFG pin. However, some hardware designs require overriding the value configured by that bootstrap pin. The PHY allows doing that by setting a bit in "PMA Receive Reserved Vendor Provisioning 1" register which allows ignoring the state of the MDI_CFG pin and another bit configuring whether the order of MDI pairs should be normal (ABCD) or reverse (DCBA). Pair polarity is not affected and remains identical in both settings. Introduce property "marvell,mdi-cfg-order" which allows forcing either normal or reverse order of the MDI pairs from DT. If the property isn't present, the behavior is unchanged and MDI pair order configuration is untouched (ie. either the result of MDI_CFG pin pull-up/pull-down, or pair order override already configured by the bootloader before Linux is started). Forcing normal pair order is required on the Adtran SDG-8733A Wi-Fi 7 residential gateway.

2024-10-08selftests: mlxsw: sch_red_core: Lower TBF ratePetr Machata
The RED test uses a pair of TBF shapers. The first to get predictably-sized stream of traffic, and second to get a 100% saturated chokepoint. To this chokepoint it injects individual packets. Because the chokepoint is saturated, these additional packets go straight to the backlog. This allows the test to check RED behavior across various queue sizes. The shapers are rated at 1Gbps, for historical reasons (before mlxsw supported TBF offload, the test used port speed to create the chokepoints). Machines with a low-power CPU may have trouble consistently generating 1Gbps of traffic, and the test then spuriously fails. Instead, drop the rate to 200Mbps (Spectrum has a guaranteed shaper rate granularity of 200Mbps, so anything lower is not guaranteed to work well). Because that means fewer packets will be mirrored in the ECN-mark test, adjust the passing condition accordingly.

2024-10-08selftests: mlxsw: sch_red_core: Send more packets for drop testsPetr Machata
This test works by injecting into a port with a maxed-out queue a couple packets and checks if a corresponding number of packets were dropped. This has worked well on Spectrum<4, but on Spectrum-4 it has been noisy. This is in line with the observation that on Spectrum-4, queue size tends to fluctuate more. A handful of packets could then still be accepted to the queue even though it was nominally full just recently. In order to accommodate this behavior, send many more packets. The buffer can fit N extra packets, but not N% packets. This therefore allows us to set wider absolute margins, while actually narrowing them relatively.

2024-10-08selftests: mlxsw: sch_red_core: Sleep before querying queue depthPetr Machata
The qdisc stats are taken from the port's periodic HW stats, which are updated once a second. We try to accommodate the latency by using busywait in build_backlog(). The issue in that seems to be that when do_mark_test() builds the backlog, it makes the decision whether to send more packets based on the first instance of the queue depth stat exceeding the current value, when in fact more traffic is on the way and the queue depth would increase further. This leads to failures in TC 1 of mark-mirror test, where we see the following failure: TEST: TC 0: marked packets mirror'd [ OK ] TEST: TC 1: marked packets mirror'd [FAIL] Spurious packets (1680 -> 2290) observed without buffer pressure Fix by waiting for the full second before reading the queue depth for the first time, to make sure it reflects all in-flight traffic.

2024-10-08selftests: mlxsw: sch_red_core: Increase backlog size tolerancePetr Machata
Backlog fluctuates on Spectrum-4 much more than on <4. In practice we can sample queue depth values going from about -12% to about +7% of the configured RED limit. The test which checks the queue size has a limit of +-10%, and as a result often fails. We attempted to fix the issue by busywaiting for several seconds hoping to get within the bounds, but that still proved to be too noisy (or the wait time would be impractically long). Unfortunately we have to bump the value tolerance from 10% to 15%, which in this patch do.

2024-10-08net: dsa: mv88e6xxx: Add FID map cacheAryan Srivastava
Add a cached FID bitmap. This mitigates the need to walk all VTU entries to find the next free FID. When flushing the VTU (during init), zero the FID bitmap. Use and manipulate this bitmap from now on, instead of reading HW for the FID map. The repeated VTU walks are costly and can take ~40 mins if ~4000 vlans are added. Caching the FID map reduces this time to <2 mins.
