Neil Armstrong says: ==================== net: ethernet: dwmac: oxnas glue removal With [1] removing MPCore SMP support, this makes the OX820 barely usable, associated with a clear lack of maintainance, development and migration to dt-schema it's clear that Linux support for OX810 and OX820 should be removed. In addition, the OX810 hasn't been booted for years and isn't even present in an ARM config file. For the OX820, lack of USB and SATA support makes the platform not usable in the current Linux support and relies on off-tree drivers hacked from the vendor (defunct for years) sources. The last users are in the OpenWRT distribution, and today's removal means support will still be in stable 6.1 LTS kernel until end of 2026. If someone wants to take over the development even with lack of SMP, I'll be happy to hand off maintainance. It has been a fun time adding support for this architecture, but it's time to get over!

Petr Machata says: ==================== selftests: New selftests for out-of-order-operations patches in mlxsw In the past, the mlxsw driver made the assumption that the user applies configuration in a bottom-up manner. Thus netdevices needed to be added to the bridge before IP addresses were configured on that bridge or SVI added on top of it, because whatever happened before a netdevice was mlxsw upper was generally ignored by mlxsw. Recently, several patch series were pushed to introduce the bookkeeping and replays necessary to offload the full state, not just the immediate configuration step. In this patchset, introduce new selftests that directly exercise the out of order code paths in mlxsw. - Patch #1 adds new tests into the existing selftest router_bridge.sh. - Patches #2-#5 add new generic selftests. - Patches #6-#8 add new mlxsw-specific selftests. ==================== Signed-off-by: -

Add two tests to deslave a port from and reenslave to a bridge. This should retain the ability of the system to forward traffic, but on an offloading driver that is sensitive to ordering of operations, it might not. The first test does this configuration in a way that relies on vlan_default_pvid to assign the PVID. The second test disables that autoconfiguration and configures PVID by hand in a separate step.

Radu Pirea says: ==================== Add TJA1120 support This patch series got bigger than I expected. It cleans up the next-c45-tja11xx driver and adds support for the TJA1120(1000BaseT1 automotive phy). Master/slave custom implementation was replaced with the generic implementation (genphy_c45_config_aneg/genphy_c45_read_status). The TJA1120 and TJA1103 are a bit different when it comes to the PTP interface. The timestamp read procedure was changed, some addresses were changed and some bits were moved from one register to another. Adding TJA1120 support was tricky, and I tried not to duplicate the code. If something looks too hacky to you, I am open to suggestions. ==================== Link: https://lore.kernel.org/r/20230731091619.77961-1-radu-nicolae.pirea@oss.nxp.com Signed-off-by:

During PTP testing on early TJA1120 engineering samples I observed that if the link is lost and recovered, the tx timestamps will be randomly lost. To avoid this HW issue, the PCS should be reset. Resetting the PCS will break the link and we should reset the PCS on LINK UP -> LINK DOWN transition, otherwise we will trigger and infinite loop of LINK UP -> LINK DOWN events. Signed-off-by:

On TJA1120, the external trigger timestamp now has a VALID bit. This changes the logic and we can't use the TJA1103 procedure. For TJA1103, we can always read a valid timestamp from the registers, compare the new timestamp with the old timestamp and, if they are not the same, an event occurred. This logic cannot be applied for TJA1120 because the timestamp is 0 if the VALID bit is not set. Signed-off-by:

TJA1120 and TJA1103 have a set of functional safety hardware tests executed after every reset, and when the tests are done, the IRQ line is asserted. For the moment, the purpose of these handlers is to acknowledge the IRQ and not to check the FUSA tests status. Signed-off-by:

The egress timestamp FIFO/circular buffer work different on TJA1120 than TJA1103. For TJA1103 the new timestamp should be manually moved from the FIFO to the hardware buffer before checking if the timestamp is valid. For TJA1120 the hardware will move automatically the new timestamp from the FIFO to the buffer and the user should check the valid bit, read the timestamp and unlock the buffer by writing any of the buffer registers(which are read only). Another change for the TJA1120 is the behaviour of the EGR TS IRQ bit. This bit was a self-clear bit for TJA1103, but now should be cleared before reading the timestamp. Signed-off-by:

This patch series add support to set or get the parameters for a specified virtqueue. When the traffic between virtqueues is unbalanced, for example, one virtqueue is busy and another virtqueue is idle, then it will be very useful to control coalescing parameters at the virtqueue granularity. Example command: $ ethtool -Q eth5 queue_mask 0x1 --coalesce tx-packets 10 Would set max_packets=10 to VQ 1. $ ethtool -Q eth5 queue_mask 0x1 --coalesce rx-packets 10 Would set max_packets=10 to VQ 0. $ ethtool -Q eth5 queue_mask 0x1 --show-coalesce Queue: 0 Adaptive RX: off TX: off stats-block-usecs: 0 sample-interval: 0 pkt-rate-low: 0 pkt-rate-high: 0 rx-usecs: 222 rx-frames: 0 rx-usecs-irq: 0 rx-frames-irq: 256 tx-usecs: 222 tx-frames: 0 tx-usecs-irq: 0 tx-frames-irq: 256 rx-usecs-low: 0 rx-frame-low: 0 tx-usecs-low: 0 tx-frame-low: 0 rx-usecs-high: 0 rx-frame-high: 0 tx-usecs-high: 0 tx-frame-high: 0 ==================== Link: https://lore.kernel.org/r/20230731070656.96411-1-gavinl@nvidia.com Signed-off-by:
