`dev_port` is used to differentiate devices that instantiate from the same function, which is the case in most of NFP NICs. In some customized scenario, `dev_port` is used to rename netdev instead of `phys_port_name`. Example rules using `dev_port`: SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="0", NAME:="ens8np0" SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="1", NAME:="ens8np1" To take port split case into account, here we initialize `dev_port` according to the port sequence in eth_table from management firmware instead of using port label id directly. And management firmware makes sure that port sequence matches its label id.

This patch adds support for platform-specific reset logic in the stmmac driver. Some SoCs require a different reset mechanism than the standard dwmac IP reset. To support these platforms, a new function pointer 'fix_soc_reset' is added to the plat_stmmacenet_data structure. The stmmac_reset in hwif.h is modified to call the 'fix_soc_reset' function if it exists. This enables the driver to use the platform-specific reset logic when necessary.

Announce that the driver supports CAN_CTRLMODE_BERR_REPORTING by means of priv->can.ctrlmode_supported. Until now berr reporting always has been active without taking care of the berr-reporting parameter given to an "ip link set ..." command. Additionally apply some changes to function esd_usb_rx_event(): - If berr reporting is off and it is also no state change, then immediately return. - Unconditionally (even in case of the above "immediate return") store tx- and rx-error counters, so directly use priv->bec.txerr and priv->bec.rxerr instead of intermediate variables. - Not directly related, but to better point out the linkage between a failed alloc_can_err_skb() and stats->rx_dropped++: Move the increment of the rx_dropped statistic counter (back) to directly behind the err_skb allocation.

Íñigo Huguet says: ==================== sfc: support unicast PTP Unicast PTP was not working with sfc NICs. The reason was that these NICs don't timestamp all incoming packets, but instead they only timestamp packets of the queues that are selected for that. Currently, only one RX queue is configured for timestamp: the RX queue of the PTP channel. The packets that are put in the PTP RX queue are selected according to firmware filters configured from the driver. Multicast PTP was already working because the needed filters are known in advance, so they're inserted when PTP is enabled. This patches add the ability to dynamically add filters for unicast addresses, extracted from the TX PTP-event packets. Since we don't know in advance how many filters we'll need, some info about the filters need to be saved. This will allow to check if a filter already exists or if a filter is too old and should be removed. Note that the previous point is unnecessary for multicast filters, but I've opted to change how they're handled to match the new unicast's filters to avoid having duplicate insert/remove_filters functions, once for each type of filter.

When sending a PTP event packet, add the correct filters that will make that future incoming unicast PTP event packets will be timestamped. The unicast address for the filter is gotten from the outgoing skb before sending it. Until now they were not timestamped because only filters that match with the PTP multicast addressed were being configured into the NIC for the PTP special channel. Packets received through different channels are not timestamped, getting "received SYNC without timestamp" error in ptp4l. Note that the inserted filters are never removed unless the NIC is stopped or reconfigured, so efx_ptp_stop is called. Removal of old filters will be handled by the next patch. Additionally, cleanup a bit efx_ptp_xmit_skb_mc to use the reverse xmas tree convention and remove an unnecessary assignment to rc variable in void function.

That will be done in the next patch.

Instead of using a fixed sized array for the PTP filters, use a list. This is not actually necessary at this point because the filters for multicast PTP are a fixed number, but this is a preparation for the following patches adding support for unicast PTP. To avoid confusion with the new struct type efx_ptp_rxfilter, change the name of some local variables from rxfilter to spec, given they're of the type efx_filter_spec.

Remove pci_clear_master to simplify the code, the bus-mastering is also cleared in do_pci_disable_device, like this: ./drivers/pci/pci.c:2197 static void do_pci_disable_device(struct pci_dev *dev) { u16 pci_command; pci_read_config_word(dev, PCI_COMMAND, &pci_command); if (pci_command & PCI_COMMAND_MASTER) { pci_command &= ~PCI_COMMAND_MASTER; pci_write_config_word(dev, PCI_COMMAND, pci_command); } pcibios_disable_device(dev); }.

We use ppdu_sts to obtain channel information from hardware, to ensure that the scan results have correct channel information. However, some of ppdu_sts that is filtered by the to_self check is also needed for the scan results. Therefore, we modify the filter part in front of CFO count.

By default the driver uses the 1M and 6M rate (0x0) for data frames in 2 GHz and 5/6 GHz bands respectively. But the rate that might not AP supported. Therefore, We modify the data lowest rate according to the lowest of AP supported rate.
