Currently the ptp initialization is spread between driver probe/open implementations, associated APIs are qede_ptp_register_phc()/qede_ptp_start(). Clubbed this functionality into single API qed_ptp_enable() to simplify the usage of qed resource locking implementation. The new API will be invoked in the probe path. Similarly the ptp clean-up code is moved to qede_ptp_disable() which gets invoked in the driver unload path.

PTP module acquires/releases the MFW resource lock while enabling/ disabling the PTP on the interface. The PF instance which has the ownership of this resource lock will get the exclusive access to the PTP clock functionality on the port.

So it can be used with all versions >= 3.0.x. Changes: * Added version element to m_can_priv structure to hold M_CAN version. * Renamed bittiming structs for version 3.0.x * Added new bittiming structs for version >= 3.1.x * Function alloc_m_can_dev takes 2 new arguments. The TX FIFO size and the base address of the module. * Chip configuration for CAN_CTRLMODE_LOOPBACK is changed: Enabled CCCR_MON bit. In combination with TEST_LBCK it activates the internal loopback mode. Leaving CCCR_MON '0' results in external loopback mode. * Clocks are temporarily enabled by platform_propbe function in order to allow read access to the Core Release register and the Control Register. Registers are used to detect M_CAN version and optional Non-ISO Feature. Initialization of M_CAN for version >= 3.1.x: * TX FIFO of M_CAN is used to transmit frames. The driver does not need to stop the tx queue after each frame sent. * Initialization of TX Event FIFO is added. * NON-ISO is fixed for all M_CAN versions < 3.2.x. Version 3.2.x _can_ have the NISO (Non-ISO) bit which can switch the mode of the M_CAN to Non-ISO mode. This bit does not have to be writeable. Therefore it is checked. If it is writable Non-ISO support is added to the controllers supported CAN modes. New Functions: * Function to check the Core Release version. The read value determines the behaviour of the driver. * Function to check if the NISO bit for version >= 3.2.x is implemented.

The PCAN-PCI Express FD has one or two CAN FD channels, depending on the model. A galvanic isolation of the CAN ports protects the electronics of the card and the respective computer against disturbances of up to 500 Volts. The PCAN-PCI Express FD can be operated with ambient temperatures in a range of -40 to +85 °C. Such boards run an extented version of the CAN-FD IP running into USB CAN-FD interfaces from PEAK-System, so this patch adds several new commands and their corresponding data types to the PEAK CAN-FD common definitions header file too.

This API provides the illusion of 'global' netfilter hooks by placing the hooks in all current and future network namespaces. In case of ipvlan the hook appears to be only needed in the namespace that contains the ipvlan master device (i.e., usually init_net), so placing them in all namespaces is not needed. This switches ipvlan driver to pernet operations, and then only registers hooks in namespaces where a ipvlan master device is set to l3s mode. Extra care has to be taken when the master device is moved to another namespace, as we might have to 'move' the netfilter hooks too. This is done by storing the namespace the ipvlan port was created in. On REGISTER event, do (un)register operations in the old/new namespaces. This will also allow removal of the nf_register_hooks() in a future patch. Cc: Mahesh Bandewar <maheshb@google.com> Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.

This enables better TCP pacing using TCP small queues and increases single stream throughput. The virtio-net driver currently cleans tx descriptors on transmission of new packets in ndo_start_xmit. Latency depends on new traffic, so is unbounded. To avoid deadlock when a socket reaches its snd limit, packets are orphaned on tranmission. This breaks socket backpressure, including TSQ. Napi increases the number of interrupts generated compared to the current model, which keeps interrupts disabled as long as the ring has enough free descriptors. Keep tx napi optional and disabled for now. Follow-on patches will reduce the interrupt cost.
