According to the definition of virtqueue coalescing spec[1]: Upon disabling and re-enabling a transmit virtqueue, the device MUST set the coalescing parameters of the virtqueue to those configured through the VIRTIO_NET_CTRL_NOTF_COAL_TX_SET command, or, if the driver did not set any TX coalescing parameters, to 0. Upon disabling and re-enabling a receive virtqueue, the device MUST set the coalescing parameters of the virtqueue to those configured through the VIRTIO_NET_CTRL_NOTF_COAL_RX_SET command, or, if the driver did not set any RX coalescing parameters, to 0. We need to add this setting for vq resize (ethtool -G) where vq_reset happens.

Background: 1. Commit 0c465be1 ("virtio_net: ethtool tx napi configuration") uses tx-frames to toggle napi_tx (0 off and 1 on) if notification coalescing is not supported. 2. Commit 31c03aef ("virtio_net: enable napi_tx by default") enables napi_tx for all txqs by default. Status: When virtio-net supports notification coalescing, after initialization, tx-frames is 0 and napi_tx is true. Problem: When the user only wants to set rx coalescing params using ethtool -C eth0 rx-usecs 10, or ethtool -Q eth0 queue_mask 0x1 -C rx-usecs 10, these cmds will carry tx-frames as 0, causing the napi_tx switching condition is satisfied. Then the user gets: netlink error: Device or resource busy. The same happens when trying to set rx-frames, adaptive_rx, adaptive_tx... How to fix: When notification coalescing feature is negotiated, initially make the value of tx-frames to be consistent with napi_tx. For compatibility with the past, it is still supported to use tx-frames to toggle napi_tx. Reported-by:

`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. ethtool_sprintf() is designed specifically for get_strings() usage.

Ethtool stats strings cannot be longer than 32 characters ('ETH_GSTRING_LEN'), including the terminating null byte. The format string '%.29s_%.1d' can exceed this limitation if the per-TC counter name exceeds 28 characters. Together with the underscore, the two digits of the TC (bounded at 16) and the terminating null byte, more than 32 characters will be used. Fix this by bounding the counter name at 28 characters which suppresses the following build warning [1]. This does not affect ethtool output since the longest counter name does not exceed this limitation.

The name of a thermal zone device cannot be longer than 19 characters ('THERMAL_NAME_LENGTH - 1'). The format string 'mlxsw-lc%d-gearbox%d' can exceed this limitation if the maximum number of line cards and the maximum number of gearboxes on each line card cannot be represented using a single digit. This is not the case with current systems nor future ones. Therefore, increase the size of the result buffer beyond 'THERMAL_NAME_LENGTH' and suppress the following build warning [1].

This commit changes the data receiver repath behavior to occur after receiving a single duplicate. This can help recover ACK connectivity quicker if a TLP was sent along a nonworking path. For instance, consider the case where we have an initially nonworking forward path and reverse path and subsequently switch to only working forward paths. Before this patch we would have the following behavior. +---------+--------+--------+----------+----------+----------+ | Event | For FL | Rev FL | FP Works | RP Works | Data Del | +---------+--------+--------+----------+----------+----------+ | Initial | A | 1 | N | N | 0 | +---------+--------+--------+----------+----------+----------+ | TLP | A | 1 | N | N | 0 | +---------+--------+--------+----------+----------+----------+ | RTO 1 | B | 1 | Y | N | 1 | +---------+--------+--------+----------+----------+----------+ | RTO 2 | C | 1 | Y | N | 2 | +---------+--------+--------+----------+----------+----------+ | RTO 3 | D | 2 | Y | Y | 3 | +---------+--------+--------+----------+----------+----------+ This patch gets rid of at least RTO 3, avoiding additional unnecessary repaths of a working forward path to a (potentially) nonworking one. In addition, this commit changes the behavior to avoid repathing upon rx of duplicate data if the local endpoint is in CA_Loss (in which case the RTOs will already be changing the outgoing flowlabel).

A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. It should be noted that there doesn't currently exist a bug here as DRV_NAME is a small string literal which means no overread bugs are present. Also to note, other ethernet drivers are using strscpy in a similar pattern: | dec/tulip/tulip_core.c | 861: strscpy(info->driver, DRV_NAME, sizeof(info->driver)); | | 8390/ax88796.c | 582: strscpy(info->driver, DRV_NAME, sizeof(info->driver)); | | dec/tulip/dmfe.c | 1077: strscpy(info->driver, DRV_NAME, sizeof(info->driver)); | | 8390/etherh.c | 558: strscpy(info->driver, DRV_NAME, sizeof(info->driver)); Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://manpages.debian.org/testing/linux-manual-4.8/strscpy.9.en.html [2] Link: https://github.com/KSPP/linux/issues/90Signed-off-by:

As we don't specify the MTU in the driver, the framework will fall back to 1500 bytes and this doesn't work very well when we try to attach a DSA switch: eth1: mtu greater than device maximum ixp4xx_eth c800a000.ethernet eth1: error -22 setting MTU to 1504 to include DSA overhead After locating an out-of-tree patch in OpenWrt I found suitable code to set the MTU on the interface and ported it and updated it. Now the MTU gets set properly. Reviewed-by:

Merge tag 'linux-can-next-for-6.7-20231005' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2023-10-05 The first patch is by Miquel Raynal and fixes a comment in the sja1000 driver. Vincent Mailhol contributes 2 patches that fix W=1 compiler warnings in the etas_es58x driver. Jiapeng Chong's patch removes an unneeded NULL pointer check before dev_put() in the CAN raw protocol. A patch by Justin Stittreplaces a strncpy() by strscpy() in the peak_pci sja1000 driver. The next 5 patches are by me and fix the can_restart() handler and replace BUG_ON()s in the CAN dev helpers with proper error handling. The last 27 patches are also by me and target the at91_can driver. First a new helper function is introduced, the at91_can driver is cleaned up and updated to use the rx-offload helper. * tag 'linux-can-next-for-6.7-20231005' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next: (37 commits) can: at91_can: switch to rx-offload implementation can: at91_can: at91_alloc_can_err_skb() introduce new function can: at91_can: at91_irq_err_line(): send error counters with state change can: at91_can: at91_irq_err_line(): make use of can_change_state() and can_bus_off() can: at91_can: at91_irq_err_line(): take reg_sr into account for bus off can: at91_can: at91_irq_err_line(): make use of can_state_get_by_berr_counter() can: at91_can: at91_irq_err(): rename to at91_irq_err_line() can: at91_can: at91_irq_err_frame(): move next to at91_irq_err() can: at91_can: at91_irq_err_frame(): call directly from IRQ handler can: at91_can: at91_poll_err(): increase stats even if no quota left or OOM can: at91_can: at91_poll_err(): fold in at91_poll_err_frame() can: at91_can: add CAN transceiver support can: at91_can: at91_open(): forward request_irq()'s return value in case or an error can: at91_can: at91_chip_start(): don't disable IRQs twice can: at91_can: at91_set_bittiming(): demote register output to debug level can: at91_can: rename struct at91_priv::{tx_next,tx_echo} to {tx_head,tx_tail} can: at91_can: at91_setup_mailboxes(): update comments can: at91_can: add more register definitions can: at91_can: MCR Register: convert to FIELD_PREP() can: at91_can: MSR Register: convert to FIELD_PREP() ... ==================== Link: https://lore.kernel.org/r/20231005195812.549776-1-mkl@pengutronix.deSigned-off-by:

This implements the led_hw_* hooks to support hardware blinking LEDs on the DP83867 phy. The driver supports all LED modes that have a corresponding TRIGGER_NETDEV_* define. Error and collision do not have a TRIGGER_NETDEV_* define, so these modes are currently not supported. Reviewed-by:

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct flow_action_entry. Cc: "David S.
