The driver uses the string "slcan" to populate tty_ldisc_ops::name. KBUILD_MODNAME also evaluates to "slcan". Use KBUILD_MODNAME to get rid on the hardcoded string names. Similarly, the pr_info() and pr_err() hardcoded the "slcan" prefix. Define pr_fmt so that the "slcan" prefix gets automatically added.

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says: ==================== The c_can, flexcan and slcan use a setter function to populate net_device::ethtool_ops. Using a setter here add one additional function call and add some small bloat in the object file. Exporting the structure allow to remove this setter. The mcp251xfd uses a similar pattern except that it does some additional initialization. As such, this driver is left untouched. * Statistics * For the slcan driver, this patch reduces the object file by 14 bytes (details in the first patch). Although we did not conduct a benchmark for the other drivers but we expect the exact same figures. ==================== Link: https://lore.kernel.org/all/20220727104939.279022-1-mailhol.vincent@wanadoo.frSigned-off-by:

The function flexcan_set_ethtool_ops() does one thing: populate net_device::ethtool_ops. Instead, it is possible to directly assign this field and remove one function call and slightly reduce the object size. To do so, export flexcan_ethtool_ops so it becomes visible to flexcan-core.c.

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says: ==================== This is a cleanup series. The patches 1 to 8 get rid of any hardcoded strings and instead relies on the KBUILD_MODNAME macros to get the device name. Patch 9 replaces the ES58X_MODULE_NAME macro with KBUILD_MODNAME in etas_es58x. Finally, also in etas_es58x, patch 10 removes the DRV_VERSION so that the module uses the default behavior and advertise the kernel version instead of a custom version. * Changelog * v1 -> v2: * The patch for esd_usb contained some changes for ems_usb. * v1 assumed that KBUILD_MODNAME could only be used when the file basename and the module had the same name (e.g. vcan.c for the vcan.ko). The fact is that KBUILD_NAME extends to the module name and can thus be used even if the basename is different (e.g. slcan-core.c and slcan.ko) * Add patch #9: can: etas_es58x: replace ES58X_MODULE_NAME with KBUILD_MODNAME v1: https://lore.kernel.org/all/20220725153124.467061-1-mailhol.vincent@wanadoo.fr This series are the first 9 patches of: https://lore.kernel.org/linux-can/20220725133208.432176-1-mailhol.vincent@wanadoo.fr/T/ The initial intent of those 9 patches was to do so cleanup in order to implement ethtool_ops::get_drvinfo but this appeared to be useless: https://lore.kernel.org/linux-can/20220725140911.2djwxfrx3kdmjeuc@pengutronix.de/ Instead, those patch are send as a standalone series. ==================== Drop "[PATCH v2 03/10] can: slcan: use KBUILD_MODNAME and define pr_fmt to replace hardcoded names" to avoid conflicts with Dario Binacchi's work on the slcan driver.

DRV_VERSION is a leftover from when the driver was an out of tree module. The driver version was never incremented despite of the numerous changes made since it was mainstreamed.

Christian Marangi says: ==================== Add MTU change with stmmac interface running This series is to permit MTU change while the interface is running. Major rework are needed to permit to allocate a new dma conf based on the new MTU before applying it. This is to make sure there is enough space to allocate all the DMA queue before releasing the stmmac driver. This was tested with a simple way to stress the network while the interface is running. 2 ssh connection to the device: - One generating simple traffic with while true; do free; done - The other making the mtu change with a delay of 1 second The connection is correctly stopped and recovered after the MTU is changed. The first 2 patch of this series are minor fixup that fix problems presented while testing this. One fix a problem when we renable a queue while we are generating a new dma conf. The other is a corner case that was notice while stressing the driver and turning down the interface while there was some traffic. (this is a follow-up of a simpler patch that wanted to add the same feature. It was suggested to first try to check if it was possible to apply the new configuration. Posting as RFC as it does major rework for the new concept of DMA conf) ==================== Link: https://lore.kernel.org/r/20220723142933.16030-1-ansuelsmth@gmail.comSigned-off-by:

Remove the limitation where the interface needs to be down to change MTU by releasing and opening the stmmac driver to set the new MTU. Also call the set_filter function to correctly init the port. This permits to remove the EBUSY error while the ethernet port is running permitting a correct MTU change if for example a DSA request a MTU change for a switch CPU port. Signed-off-by:

Currently, the reading of FRC values (high and low) is done using macro which calls to a function. In addition, to calculate the offset of FRC, a simple macro is used. This code can be simplified by adding an helper function and calculating the offset explicitly instead of using an additional macro for that. Add the helper function and convert the existing code. This helper will be used later to read UTC clock. Signed-off-by:

As lately recommended in the mailing list[1], set the clock to zero time as part of initialization. The idea is that when the clock reads 'Jan 1, 1970', then it is clearly wrong and user will not mistakenly think that the clock is set correctly. If as part of initialization, the driver sets the clock, user might see correct date and time (maybe with a small shift) and assume that there is no need to sync the clock. Fix the existing code of Spectrum-1 to set the 'timecounter' to zero. [1]: https://lore.kernel.org/netdev/20220201191041.GB7009@hoboy.vegasvil.org/Signed-off-by:
