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.

This works in the same way as patch from Bobby Eshleman: commit c43170b7 ("vsock: return errors other than -ENOMEM to socket"), but for receive calls. VMCI transport is also updated (both tx and rx SOCK_STREAM callbacks), because it returns VMCI specific error code to af_vsock.c (like VMCI_ERROR_*). Tx path is already merged to net, so it was excluded from patchset in v4.

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. Tested: With ptp4l, all combinations of IPv4/IPv6, master/slave and unicast/multicast Reported-by: Yalin Li <yalli@redhat.com> ==================== Link: https://lore.kernel.org/r/20230331111404.17256-1-ihuguet@redhat.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

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.

Add a second list for unicast filters and generalize the efx_ptp_insert/remove_filters functions to allow acting in any of the 2 lists. No filters for unicast are inserted yet. That will be done in the next patch. The reason to use 2 different lists instead of a single one is that, in next patches, we will want to check if unicast filters are already added and if they're expired. We don't need that for multicast filters.

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.

Daniel Golle says: ==================== net: dsa: add support for MT7988 The MediaTek MT7988 SoC comes with a built-in switch very similar to previous MT7530 and MT7531. However, the switch address space is mapped into the SoCs memory space rather than being connected via MDIO. Using MMIO simplifies register access and also removes the need for a bus lock, and for that reason also makes interrupt handling more light-weight. Note that this is different from previous SoCs like MT7621 and MT7623N which also came with an integrated MT7530-like switch which yet had to be accessed via MDIO. Split-off the part of the driver registering an MDIO driver, then add another module acting as MMIO/platform driver. The whole series has been tested on various MediaTek boards: * MT7623A + MT7530 (BPi-R2) * MT7986A + MT7531 (BPi-R3) * MT7988A reference board Changes since v1: * use 'internal' PHY mode where appropriate * use regmap_update_bits in mt7530_rmw * improve dt-bindings Changes since RFC v3: * WARN_ON_ONCE if register read fails * move probing of the reset GPIO and reset controller link out of common probe function, as they are not actually common Changes since RFC v2: * split into many small commits to ease review * introduce helper functions to reduce code duplication * use helpers for locking to make lock-skipping easier and less ugly to implement. * add dt-bindings for mediatek,mt7988-switch Changes since initial RFC: * use regmap for register access and move register access to bus- specific driver * move initialization of MT7531 SGMII PCS to MDIO driver ==================== Signed-off-by: David S.

Add driver for the built-in Gigabit Ethernet switch which can be found in the MediaTek MT7988 SoC.

Daniel Golle authored
As MT7530 and MT7531 internally use 32-bit wide registers, each access to any register of the switch requires several operations on the MDIO bus. Hence if there is congruent access, e.g. due to PCS or PHY polling, this can mess up and interfere with another ongoing register access sequence. However, the MDIO bus mutex is only relevant for MDIO-connected switches. Prepare switches which have there registers directly mapped into the SoCs register space via MMIO which do not require such locking. There we can simply use regmap's default locking mechanism. Hence guard mutex operations to only be performed in case of MDIO connected switches.

Before this patch set, DSA prevented the conversion of any networking driver from the ndo_eth_ioctl() API to the ndo_hwtstamp_set() API, because it wanted to validate the hwtstamping settings on the DSA master, and it was only coded up to do this using the old API. After this patch set, a new netdev notifier exists, which does not depend on anything that would constitute the "soon-to-be-legacy" API, but rather, it uses a newly introduced struct kernel_hwtstamp_config, and it doesn't issue any ioctl at all, being thus compatible both with ndo_eth_ioctl(), and with the not-yet-introduced, but now possible, ndo_hwtstamp_set(). ==================== Signed-off-by: David S.
