This patch adds u64_stats_update_* usage to protect access to 64-bit stats, where necessary. This is necessary for per-ring stats, because they are updated by the driver directly, so there is a possibility for a partial read. Other stats require no additional protection, e.g.: * all MACSec stats are fetched directly from HW (under semaphore); * nic/ndev stats (aq_stats_s) are fetched directly from FW (under mutex).

Mark Starovoytov authored
This patch replaces addition assignment operator with a simple assignment in aq_vec_get_stats() and aq_vec_get_sw_stats(), because it is sufficient in both cases and this change simplifies the introduction of u64_stats_update_* in these functions. Signed-off-by:

Vladimir Oltean says: ==================== Extend testptp with PTP perout waveform Demonstrate the usage of the newly introduced flags in the PTP_PEROUT_REQUEST2 ioctl: https://www.spinics.net/lists/netdev/msg669346.html ==================== Signed-off-by:

Vladimir Oltean authored
Extend the example program for PTP ancillary functionality with the ability to configure not only the periodic output's period (frequency), but also the phase and duty cycle (pulse width) which were newly introduced. The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2, since the original PTP_PEROUT_REQUEST doesn't support this functionality. For an in-tree testing program, not having explicit backwards compatibility is fine, as it should always be tested with the current kernel headers and sources. Tested with an oscilloscope on the felix switch PHC: echo '2 0' > /sys/class/ptp/ptp1/pins/switch_1588_dat0 ./testptp -d /dev/ptp1 -p 1000000000 -w 100000000 -H 1000 -i 0 Signed-off-by:

Since 'perout' holds the nanosecond value of the signal's period, it should be a 64-bit value. Current assumption is that it cannot be larger than 1 second. Signed-off-by:

Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. This driver makes use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), pci_set_power_state() and pci_set_master() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use to_pci_dev() and dev_get_drvdata() to get "struct pci_dev*" variable and drv data. Compile-tested only. Signed-off-by:

Alexander Lobakin says: ==================== qed, qede: add support for new operating modes This series covers the support for the following: - new port modes; - loopback modes, previously missing; - new speed/link modes; - several FEC modes; - multi-rate transceivers; and also cleans up and optimizes several related parts of code. v3 (from [2]): - dropped custom link mode declaration; qed, qede and qedf switched to Ethtool link modes and definitions (#0001, #0002, per Andrew Lunn's suggestion); - exchange more .text size to .initconst and .ro_after_init in qede (#0003). v2 (from [1]): - added a patch (#0010) that drops discussed dead struct member; - addressed checkpatch complaints on #0014 (former #0013); - rebased on top of latest net-next; - no other changes.

Currently qed driver does not take into consideration transceiver's capabilities when generating link partner's speed advertisement. This leads to e.g. incorrect ethtool link info on 10GbaseT modules. Use transceiver info not only for advertisement and support arrays, but also for link partner's abilities to fix it.

Currently qed driver already ran out of 32 bits to store link modes, and this doesn't allow to add and support more speeds. Convert custom link mode to generic Ethtool bitmap and definitions (convenient Phylink shorthands are used for elegance and readability). This allowed us to drop all conversions/mappings between the driver and Ethtool. This involves changes in qede and qedf as well, as they used definitions from shared "qed_if.h". Suggested-by:

Merge tag 'wireless-drivers-next-2020-07-20' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for v5.9 First set of patches for v5.9. This comes later than usual as I was offline for two weeks. The biggest change here is moving Microchip wilc1000 driver from staging. There was an immutable topic branch with one commit moving the whole driver and the topic branch was pulled both to staging-next and wireless-drivers-next. At the moment the only reported conflict is in MAINTAINERS file, so I'm hoping the move should go smoothly. Other notable changes are ath11k getting 6 GHz band support and rtw88 supporting RTL8821CE. And there's also the usual fixes, API changes and cleanups all over. Major changes: wilc1000 * move from drivers/staging to drivers/net/wireless/microchip ath11k * add 6G band support * add spectral scan support iwlwifi * make FW reconfiguration quieter by not using warn level rtw88 * add support for RTL8821CE ==================== Signed-off-by:

Nicolas Ferre says: ==================== net: macb: Wake-on-Lan magic packet GEM and MACB handling Here is the second part of support for WoL magic-packet on the current macb driver. This one is addressing the bulk of the feature and is based on current net-next/master. MACB and GEM code must co-exist and as they don't share exactly the same register layout, I had to specialize a bit the suspend/resume paths and plug a specific IRQ handler in order to avoid overloading the "normal" IRQ hot path. These changes were tested on both sam9x60 which embeds a MACB+FIFO controller and sama5d2 which has a GEM+packet buffer type of controller. Best regards, Nicolas Changes in v7: - Release the spinlock before exiting macb_suspend/resume in case of error changing IRQ handler Changes in v6: - rebase on net-next/master now that the "fixes" patches of the series are merged in both net and net-next. - GEM addition and MACB update to finish the support of WoL magic-packet on the two revisions of the controller. ==================== Signed-off-by: -

Handle the Wake-on-Lan interrupt for the Cadence MACB Ethernet controller. As we do for the GEM version, we handle of WoL interrupt in a specialized interrupt handler for MACB version that is positionned just between suspend() and resume() calls.

Adapt the Wake-on-Lan feature to the Cadence GEM Ethernet controller. This controller has different register layout and cannot be handled by previous code. We disable completely interrupts on all the queues but the queue 0. Handling of WoL interrupt is done in another interrupt handler positioned depending on the controller version used, just between suspend() and resume() calls. It allows to lower pressure on the generic interrupt hot path by removing the need to handle 2 tests for each IRQ: the first figuring out the controller revision, the second for actually knowing if the WoL bit is set.

Florian Fainelli says: ==================== net: dsa: Setup dsa_netdev_ops This patch series addresses the overloading of a DSA CPU/management interface's netdev_ops for the purpose of providing useful information from the switch side. Up until now we had duplicated the existing netdev_ops structure and added specific function pointers to return information of interest. Here we have a more controlled way of doing this by involving the specific netdev_ops function pointers that we want to be patched, which is easier for auditing code in the future. As a byproduct we can now maintain netdev_ops pointer comparisons which would be failing before (no known in tree problems because of that though). Let me know if this approach looks reasonable to you and we might do the same with our ethtool_ops overloading as well. Changes in v2: - use static inline int vs. static int inline (Kbuild robot) - fixed typos in patch 4 (Andrew) - avoid using macros (Andrew) ==================== Signed-off-by:
