Currently NOLOCK qdiscs pay a measurable overhead to atomically manipulate the __QDISC_STATE_RUNNING. Such bit is flipped twice per packet in the uncontended scenario with packet rate below the line rate: on packed dequeue and on the next, failing dequeue attempt. This changeset moves the bit manipulation into the qdisc_run_{begin,end} helpers, so that the bit is now flipped only once per packet, with measurable performance improvement in the uncontended scenario. This also allows simplifying the qdisc teardown code path - since qdisc_is_running() is now effective for each qdisc type - and avoid a possible race between qdisc_run() and dev_deactivate_many(), as now the some_qdisc_is_busy() can properly detect NOLOCK qdiscs being busy dequeuing packets.

In a mixed environment it may be difficult to tell if your hardware support carrier, if it does not it can always report true. With a new use_carrier option of 2, we can check both carrier and link status sequentially, instead of one or the other Signed-off-by:

The rx load balancing provided by balance-alb is not mutually exclusive with using hashing for tx selection, and should provide a decent speed increase because this eliminates spinlocks and cache contention. Signed-off-by:

SMC handles deferred work in tasklets. As tasklets cannot sleep this can result in rare EBUSY conditions, so defer this work in a work queue. The high level api functions do not defer work because they can sleep until the llc send is actually completed. Signed-off-by:

And to send a test_link response set the response flag and send the message back as-is, without using smc_llc_send_test_link().

If TCP_NODELAY is set or TCP_CORK is reset, setsockopt triggers the tx worker. This does not make sense, if the SMC socket switched to the TCP fallback when the connection is created. This patch adds the additional check for the fallback case. Signed-off-by:

We call pcim_iomap in hclge_pci_init, pcim_iounmap should be called in error handle of hclge_init_ae_dev. We call pcim_iomap in hclge_pci_init, but do not call pcim_iounmap in hclge_pci_uninit. When we remove the hclge.ko and insert it again, a problem that pci can not map will happen. pcim_iounmap need to be called in hclge_pci_uninit.

When hclge_ae_start is called, hdev->hw.mac.link may be set to one after up/down multi-times, which does not correspond to the link state of netdev when the netdev is up.

A client includes many client instance. Just like ae_algo, Initializing client instance failed does not represent registering client failed. The action of registering client just is adding client to the client list and the result always is true. This patch changes the return value of hnae3_register_client form a variable value to a fixed value, makes the function always return ok. Signed-off-by:

The ae_algo is used by many ae_devs. It is not only belong to just a ae_dev. Initializing ae_dev failed does not represent registering ae_algo failed. Because the action of registering ae_algo just is adding ae_algo to the ae_algo list and it is always is true, it make no sense to define return type as int. This patch changes the return type of hnae3_register_ae_algo from int to void. Signed-off-by:

If hclge.ko has not been inserted, the value of ret always is zero in hnae3_register_ae_dev. If hclge.ko has been inserted, the value of ret is zero or non zero. Different execution ways have different results. It is confusing. The ae_dev which is initialized failed can be reinitialized when we remove hclge.ko and insert it again. For the case initializing client instance, it is just like the case initializing ae_dev. The main function of hnae3_register_ae_dev is adding the ae_dev to ad_dev list. Because adding ae_dev is always ok, we does not need to return any in this function. This patch changes the return type of hnae3_register_ae_dev from int to void. Signed-off-by:

When initializing ae_dev failed during loading hclge.ko, the drvdata will be set to null. When removing hns3.ko, we get a null ae_dev. It causes the null pointer problem. This patch removes pci_set_drvdata from error handle of hclge_init_ae_dev to fix the bug, since pci_set_drvdata has been called in hns3_remove. Also, we do not need to uninit the ae_dev which is not initialized. And it may be the one which is initialized failed.

When hnae3_unregister_ae_algo is called by PF, pci_disable_sriov is called. And then, hns3_remove is called by VF. We get deadlocked in this case. Since VF pci device is dependent on PF pci device, When PF pci device is removed, VF pci device must be removed. Also, To solve the deadlock problem, VF pci device should be removed before PF pci device is removed. This patch moves pci_enable/disable_sriov from hclge to hns3 to solve the deadlock problem. Also, we do not need to return EPROBE_DEFER in hnae3_register_ae_dev, because SRIOV is no longer enabled in the context calling hnae3_register_ae_dev. Mutex_trylock can be replaced with mutex_lock.

Alexandre Belloni says: ==================== Microsemi Ocelot Ethernet switch support This series adds initial support for the Microsemi Ethernet switch present on Ocelot SoCs. This only has bridging (and STP) support for now and it uses the switchdev framework. Coming features are VLAN filtering, link aggregation, IGMP snooping. The switch can also be connected to an external CPU using PCIe. Also, support for integration on other SoCs will be submitted. The ocelot dts changes are here for reference and should probably go through the MIPS tree once the bindings are accepted. Changes in v3: - Collected Reviewed-by * Switchdev driver: - Fixed two issues reported by kbuild - Modified ethtool statistics to support different layoiut on different chips and take care of counter overflow Changes in v2: - Dropped Microsemi Ocelot PHY support * MIIM driver: - Documented interrupts bindings - Moved the driver to drivers/net/phy/ - Removed unused mutex - Removed MDIO bus scanning * Switchdev driver: - Changed compatible to mscc,vsc7514-switch - Removed unused header inclusion - Factorized MAC table selection in ocelot_mact_select() - Disable the port in ocelot_port_stop() - Fixed the smatch endianness warnings - int to unsinged int where necessary - Removed VID handling for the FDB it has been reworked anyway and will be submitted with VLAN support - Fixed up unused cases in ocelot_port_attr_set() - Added a loop to register all the IO register spaces - the ports are now in an ethernet-ports node I've tried switching to NAPI but this is not working well, mainly because the only way to disable interrupts is to actually mask them in the interrupt controller (it is not possible to tell the switch to stop generating interrupts). ==================== Signed-off-by: -

Add a driver for Microsemi Ocelot Ethernet switch support. This makes two modules: mscc_ocelot_common handles all the common features that doesn't depend on how the switch is integrated in the SoC. Currently, it handles offloading bridging to the hardware. ocelot_io.c handles register accesses. This is unfortunately needed because the register layout is packed and then depends on the number of ports available on the switch. The register definition files are automatically generated. ocelot_board handles the switch integration on the SoC and on the board. Frame injection and extraction to/from the CPU port is currently done using register accesses which is quite slow. DMA is possible but the port is not able to absorb the whole switch bandwidth.
