microchip: lan865x: Fix LAN8651 autoloading

2025-08-30T02:42:07+00:00

Add missing IDs for LAN8651 devices, which are also defined in the DT bindings.

microchip: lan865x: Fix module autoloading

2025-08-30T02:42:07+00:00

Add MODULE_DEVICE_TABLE(), so modules could be properly autoloaded based on the alias from spi_device_id table. While at this, fix the misleading variable name (spidev is unrelated to this driver).

microchip: lan865x: fix missing Timer Increment config for Rev.B0/B1

2025-08-20T02:38:25+00:00

Fix missing configuration for LAN865x silicon revisions B0 and B1 as per Microchip Application Note AN1760 (Rev F, June 2024). The Timer Increment register was not being set, which is required for accurate timestamping. As per the application note, configure the MAC to set timestamping at the end of the Start of Frame Delimiter (SFD), and set the Timer Increment register to 40 ns (corresponding to a 25 MHz internal clock).

microchip: lan865x: fix missing netif_start_queue() call on device open

2025-08-20T02:38:25+00:00

This fixes an issue where the transmit queue is started implicitly only the very first time the device is registered. When the device is taken down and brought back up again (using `ip` or `ifconfig`), the transmit queue is not restarted, causing packet transmission to hang. Adding an explicit call to netif_start_queue() in lan865x_net_open() ensures the transmit queue is properly started every time the device is reopened.

net: lan743x: fix potential out-of-bounds write in lan743x_ptp_io_event_clock_get()

2025-06-19T13:32:14+00:00

Before calling lan743x_ptp_io_event_clock_get(), the 'channel' value is checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8). This seems correct and aligns with the PTP interrupt status register (PTP_INT_STS) specifications. However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with only LAN743X_PTP_N_EXTTS(4) elements, using channel as an index: lan743x_ptp_io_event_clock_get(..., u8 channel,...) { ... /* Update Local timestamp */ extts = &ptp->extts[channel]; extts->ts.tv_sec = sec; ... } To avoid an out-of-bounds write and utilize all the supported GPIO inputs, set LAN743X_PTP_N_EXTTS to 8. Detected using the static analysis tool - Svace.

eth: lan743x: migrate to new RXFH callbacks

2025-06-17T01:14:25+00:00

Migrate to new callbacks added by commit 9bb00786fc61 ("net: ethtool: add dedicated callbacks for getting and setting rxfh fields"). This driver's RXFH config is read only / fixed so the conversion is purely factoring out the handling into a helper.

net: lan966x: Make sure to insert the vlan tags also in host mode

2025-05-29T13:48:37+00:00

When running these commands on DUT (and similar at the other end) ip link set dev eth0 up ip link add link eth0 name eth0.10 type vlan id 10 ip addr add 10.0.0.1/24 dev eth0.10 ip link set dev eth0.10 up ping 10.0.0.2 The ping will fail. The reason why is failing is because, the network interfaces for lan966x have a flag saying that the HW can insert the vlan tags into the frames(NETIF_F_HW_VLAN_CTAG_TX). Meaning that the frames that are transmitted don't have the vlan tag inside the skb data, but they have it inside the skb. We already get that vlan tag and put it in the IFH but the problem is that we don't configure the HW to rewrite the frame when the interface is in host mode. The fix consists in actually configuring the HW to insert the vlan tag if it is different than 0. Reviewed-by: Maxime Chevallier Fixes: 6d2c186afa5d ("net: lan966x: Add vlan support.")
