2019-01-24r8169: factor out PHY init sequence adjusting 10M and ALDPSHeiner Kallweit
Few chip versions use the same sequence to adjust 10M and ALDPS, so let's factor it out. This patch also fixes a (most likely) typo in rtl8168g_1_hw_phy_config. There bit 8 in reg 0x14 on page 0x0bcc was set and not cleared. According to the vendor driver this bit needs to be cleared in all cases.

2019-01-24net: phy: warn if phy_start is called from invalid stateHeiner Kallweit
phy_start() should be called from states PHY_READY or PHY_HALTED only. Check for this to detect misbehaving drivers. Also the state machine should be started only when being called from one of the valid states. Some more background: For all invalid states phy_start() basically was a no-op. All it did was triggering a state machine run, but for all "running" states the poll loop was active anyway. And if called from PHY_DOWN, the state machine does nothing. v3: - extended commit message Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The state machine is a no-op before phy_start() has been called. Therefore let's enable it in phy_start() only. In phy_start() let's call phy_start_machine() instead of phy_trigger_machine(). phy_start_machine is an alias for phy_trigger_machine but it makes clearer that we start the state machine here instead of just triggering a run.

2019-01-24enetc: Add RFS and RSS supportClaudiu Manoil
A ternary match table is used for RFS. If multiple entries in the table match, the entry with the lowest numerical values index is chosen as the matching entry. Entries in the table are identified using an index which takes a value from 0 to PRFSCAPR[NUM_RFS]-1 when accessed by the PSI (PF). Portions of the RFS table can be assigned to each SI by the PSI (PF) driver in PSIaRFSCFGR. Assignments are cumulative, the entries assigned to SIn start after those assigned to SIn-1. The total assignments to all SIs must be equal to or less than the number available to the port as found in PRFSCAPR. For RSS, the Toeplitz hash function used requires two inputs, a 40B random secret key that is supplied through the PRSSKR0-9 registers as well as the relevant pieces of the packet header (n-tuple). The 6 LSB bits of the hash function result will then be used as a pointer to obtain the tag referenced in the 64 entry indirection table. The result will provide a winning group which will be used to help route the received packet.

2019-01-24enetc: Add vf to pf messaging supportClaudiu Manoil
VSIs (VFs) may send a message to the PSI (PF) for general notification or to gain access to hardware resources which requires host inspection. These messages may vary in size and are handled as a partition copy between two memory regions owned by the respective participants. The PSI will respond with fail or success and a 16-bit message code. The patch implements the vf to pf messaging mechanism above and, as the first application making use of this support, it enables the VF to configure its own primary MAC address.

2019-01-24enetc: Introduce basic PF and VF ENETC ethernet driversClaudiu Manoil
ENETC is a multi-port virtualized Ethernet controller supporting GbE designs and Time-Sensitive Networking (TSN) functionality. ENETC is operating as an SR-IOV multi-PF capable Root Complex Integrated Endpoint (RCIE). As such, it contains multiple physical (PF) and virtual (VF) PCIe functions, discoverable by standard PCI Express. Introduce basic PF and VF ENETC ethernet drivers. The PF has access to the ENETC Port registers and resources and makes the required privileged configurations for the underlying VF devices. Common functionality is controlled through so called System Interface (SI) register blocks, PFs and VFs own a SI each. Though SI register blocks are almost identical, there are a few privileged SI level controls that are accessible only to PFs, and so the distinction is made between PF SIs (PSI) and VF SIs (VSI). As such, the bulk of the code, including datapath processing, basic h/w offload support and generic pci related configuration, is shared between the 2 drivers and is factored out in common source files (i.e. enetc.c). Major functionalities included (for both drivers): MSI-X support for Rx and Tx processing, assignment of Rx/Tx BD ring pairs to MSI-X entries, multi-queue support, Rx S/G (Rx frame fragmentation) and jumbo frame (up to 9600B) support, Rx paged allocation and reuse, Tx S/G support (NETIF_F_SG), Rx and Tx checksum offload, PF MAC filtering and initial control ring support, VLAN extraction/ insertion, PF Rx VLAN CTAG filtering, VF mac address config support, VF VLAN isolation support, etc. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: David S.

Spectrum-1 and Spectrum-2 are largely backward compatible with regards to VXLAN. One difference - as explained in previous patch - is that an underlay RIF needs to be specified instead of an underlay VR during NVE initialization. This is accomplished by calling the relevant function that returns the index of such a RIF based on the table ID (RT_TABLE_MAIN) where underlay look up occurs. The second difference is that VXLAN learning (snooping) is controlled via a different register (TNPC).

2019-01-22ptp: add debugfs support for ptp_qoriqYangbo Lu
This patch is to add debugfs support for ptp_qoriq. Current debugfs supports to control fiper1/fiper2 loopback mode. If the loopback mode is enabled, the fiper1/fiper2 pulse is looped back into trigger1/ trigger2 input. This is very useful for validating hardware and driver without external hardware. Below is an example to enable fiper1 loopback. echo 1 > /sys/kernel/debug/2d10e00.ptp_clock/fiper1-loopback Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S.

2019-01-22ptp_qoriq: support external trigger stamp FIFOYangbo Lu
The external trigger stamp FIFO was introduced as a new feature for QorIQ 1588 timer IP block. This patch is to support it by adding a new dts property "fsl,extts-fifo". Any QorIQ 1588 timer supporting this feature is required to add this property in its dts node. In addition, the FIFO should be cleaned up before enabling external trigger interrupts. Otherwise, there will be interrupts immediately just after enabling external trigger interrupts.

2019-01-22ptp_qoriq: fix interrupt enabling and handlingYangbo Lu
The tmr_tevent register would update event bits no matter tmr_temask bits were set or not. So we should get interrupts by tmr_tevent & tmr_temask, and clean up interrupts in tmr_tevent before enabling them. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S.
