| * alx: enable multiple tx queuesTobias Regnery2016-11-161-2/+6
| | | | | | | | | | | | | | | | | | | | Enable multiple tx queues by default based on the number of online cpus. The hardware supports up to four tx queues.

| * alx: enable msi-x interrupts by defaultTobias Regnery2016-11-161-5/+1Star
| | | | | | | | | | | | | | | | | | | | Remove the module parameter to enable msi-x support and enable msi-x interrupts unconditionally by default. This is a preparatory step to enable multi queue support by default, because this is only working with msi-x interrupts.

| * alx: prepare tx path for multi queue supportTobias Regnery2016-11-161-13/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch prepares the tx path to send data on multiple tx queues. It introduces per queue register adresses and uses them in the alx_tx_queue structs. There are new helper functions for the queue mapping in the tx path.

| * alx: prepare interrupt functions for multiple queuesTobias Regnery2016-11-161-27/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | Extend the interrupt bringup code and the interrupt handler for msi-x interrupts in order to handle multiple queues. We must change the poll function because with multiple queues it is possible that an alx_napi structure has only a tx or only a rx queue pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new functions to allocate and free the alx_napi structures and use them in __alx_open and __alx_stop. We only allocate one of these structures for now, as the rest of the driver is not yet ready for multiple queues. We switch over the setup of the interrupt mask and the call to netif_napi_add to the new function because we must adjust these later on a per queue basis.

This version includes changes following the feedback received on previous versions from Eric Dumazet, Bob Cochran, Joe Perches, Paul Bolle, Joakim Tjernlund, Scott Wood, David Miller - thank you. Together with the driver a managed version of alloc_percpu is provided that simplifies the release of per-CPU memory. The Freescale DPAA architecture consists in a series of hardware blocks that support the Ethernet connectivity. The Ethernet driver depends upon the following drivers that are currently in the Linux kernel: - Peripheral Access Memory Unit (PAMU) drivers/iommu/fsl_* - Frame Manager (FMan) added in v4.4 drivers/net/ethernet/freescale/fman - Queue Manager (QMan), Buffer Manager (BMan) added in v4.9-rc1 drivers/soc/fsl/qbman dpaa_eth interfaces mapping to FMan MACs: dpaa_eth /eth0\ ... /ethN\ driver | | | | ------------- ---- ----------- ---- ------------- -Ports / Tx Rx \ ... / Tx Rx \ FMan | | | | -MACs | MAC0 | | MACN | / dtsec0 \ ... / dtsecN \ (or tgec) / \ / \(or memac) --------- -------------- --- -------------- --------- FMan, FMan Port, FMan SP, FMan MURAM drivers --------------------------------------------------------- FMan HW blocks: MURAM, MACs, Ports, SP --------------------------------------------------------- dpaa_eth relation to QMan, FMan: ________________________________ dpaa_eth / eth0 \ driver / \ --------- -^- -^- -^- --- --------- QMan driver / \ / \ / \ \ / | BMan | |Rx | |Rx | |Tx | |Tx | | driver | --------- |Dfl| |Err| |Cnf| |FQs| | | QMan HW |FQ | |FQ | |FQ | | | | | / \ / \ / \ \ / | | --------- --- --- --- -v- --------- | FMan QMI | | | FMan HW FMan BMI | BMan HW | ----------------------- -------- where the acronyms used above (and in the code) are: DPAA = Data Path Acceleration Architecture FMan = DPAA Frame Manager QMan = DPAA Queue Manager BMan = DPAA Buffers Manager QMI = QMan interface in FMan BMI = BMan interface in FMan FMan SP = FMan Storage Profiles MURAM = Multi-user RAM in FMan FQ = QMan Frame Queue Rx Dfl FQ = default reception FQ Rx Err FQ = Rx error frames FQ Tx Cnf FQ = Tx confirmation FQ Tx FQs = transmission frame queues dtsec = datapath three speed Ethernet controller (10/100/1000 Mbps) tgec = ten gigabit Ethernet controller (10 Gbps) memac = multirate Ethernet MAC (10/100/1000/10000) Changes from v7: - remove the debug option to use a common buffer pool for all the interfaces Changed from v6: - fixed an issue on an error path in dpaa_set_mac_address() - removed NDO operation definitions that were not needed - sorted the local variable declarations - cleaned up a few checkpatch checks - removed friendly network interface naming code Changes from v5: - adapt to the latest Q/BMan drivers API - use build_skb() on Rx path instead of buffer pool refill path - proper support for multiple buffer pools - align function, variable names, code cleanup - driver file structure cleanup Changes from v4: - addressed feedback from Scott Wood and Joe Perches - fixed spelling - fixed leak of uninitialized stack to userspace - fix prints - replace raw_cpu_ptr() with this_cpu_ptr() - remove _s from the end of structure names - remove underscores at start of functions, goto labels - remove likely in error paths - use container_of() instead of open casts - remove priv from the driver name - move return type on same line with function name - drop DPA_READ_SKB_PTR/DPA_WRITE_SKB_PTR Changes from v3: - removed bogus delay and comment in .ndo_stop implementation - addressed minor issues reported by David Miller Changes from v2: - removed debugfs, moved exports to ethtool statistics - removed congestion groups Kconfig params Changes from v1: - bpool level Kconfig options removed - print format using pr_fmt, cleaned up prints - __hot/__cold removed - gratuitous unlikely() removed - code style aligned, consistent spacing for declarations - comment formatting ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EMAC EMAC_RX_IO_DATA_REG data register is dual-purpose: On one hand it is used to move actual packet data off the wire. This will be in wire-format and accepted as such by higher layers such as IP. Therefore it is correctly read as-is (i.e. raw) using readsl. On the other hand it provides metadata about incoming transfers to the driver such as length and checksum validation status. This data is little-endian, always and it is interpreted by the driver. Therefore it needs to be swapped to CPU endianness to make sense to the driver. This is already done for the "receive header" but not rxhdr. Read rxhdr using readl in order for sun4i-emac to work correctly when running a big-endian kernel.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Florian Fainelli says: ==================== net: phy: Centralize auto-negotation restart This patch series centralizes how ethtool::nway_reset is implemented by providing a PHYLIB function which calls into genphy_restart_aneg(). All drivers below are converted to use this new helper function. Some other have specific requirements that make them not quite suitable for a straight forward conversion. There is another patch series which implements ethtool::nway_reset using the helper function introduced that depends on this patch series. ==================== Signed-off-by: David S.
