  • Refactor RGMII 10 Mbps preamble error checking. The current implementation
    does not work correctly in phydev mode since only the link status changes
    trigger the callback, and if we stay on 10 Mbps operation the periodic
    checks for error counters are never done.

    Provide a periodic worker also during the phydev operation, and notify
    the link status changes through the phydev instead of the inband
    status change interrupt. This also has the benefit that we don't need
    to use legacy CVMX MDIO calls to check the PHY state, and we can avoid
    races that trigger bogus "Using 10Mbps with software preamble removal"
    logs when interfaces are being bringed up. It also avoids some corner-case
    crashes when the in-band interrupt triggers while the interface is
    being taken down.

    Tested on EdgeRouter Lite & D-Link DSR-1000N.

  • Only wake tx queue when driver queue is back within bounds.

    The logic here was just reenabling the queue when any buffers had been
    freed. the queue was stopped whenever the length exceeded 1000
    (MAX_OUT_QUEUE_DEPTH), but then was essentially immediately started again.
    On a congested link, the queue length would just keep increasing up to
    around 8000 (for average size packets), at which point the hardware would
    start refusing the packets and they would begin to be dropped.
    This prevented the qdisc layer from effectively managing and prioritising
    packets, as essentially all packets were being allowed into the driver
    queue and then were being dropped by the hardware.

    This change only restarts the queue if the length is less than 1000
    (MAX_OUT_QUEUE_DEPTH).

  • If the network portion of a frame is preceded by more than 14 bytes of
    data, the checksum calculated in the HW is done over the wrong data and
    is put in the wrong place.
    In our use case an Octeon ethernet controller is connected to a Broadcom
    switch chip. Extra data is included in the frame prior to egressing the
    Octeon ethernet (i.e. 4 bytes of an 802.1Q tag, 4 bytes of a proprietary
    BCM tag later stripped by the switch chip). This extra data causes the
    checksum calculation to be incorrect.
    The fix in this patch is to make use of the network header offset of the
    skb. This enables the checksum to be calculated correctly.
    This has been tested in both the configuration with the switch chip in
    the egress path (as described above) and in a simple connection direct
    to the wire.

  • Pull MIPS updates from Ralf Baechle:
    "This is the main pull request for 4.3 for MIPS. Here's the summary:

    Three fixes that didn't make 4.2-stable:

    - a -Os build might compile the kernel using the MIPS16 instruction
    set but the R2 optimized inline functions in are
    implemented using 32-bit wide instructions which is invalid.

    - a build error in pgtable-bits.h for a particular kernel
    configuration.

    - accessing registers of the CM GCR might have been compiled to use
    64 bit accesses but these registers are onl 32 bit wide.

    And also a few new bits:

    - move the ATH79 GPIO driver to drivers/gpio

    - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
    change ATH79 accordingly.

    - fix definition of pgprot_writecombine

    - add an implementation of dma_map_ops.mmap

    - fix alignment of quiet build output for vmlinuz link

    - BCM47xx: Use kmemdup rather than duplicating its implementation

    - Netlogic: Fix 0x0x prefixes of constants.

    - merge Bjorn Helgaas' series to remove most of the weak keywords
    from function declarations.

    - CP0 and CP1 registers are best considered treated as unsigned
    values to avoid large values from becoming negative values.

    - improve support for the MIPS GIC timer.

    - enable common clock framework for Malta and SEAD3.

    - a number of improvments and fixes to dump_tlb().

    - document the MIPS TLB dump functionality in Magic SysRq.

    - Cavium Octeon CN68XX improvments.

    - NetLogic improvments.

    - irq: Use access helper irq_data_get_affinity_mask.

    - handle MSA unaligned accesses.

    - a number of R6-related math-emu fixes.

    - support for I6400.

    - improvments to MSA support.

    - add uprobes support.

    - move from deprecated __initcall to arch_initcall.

    - remove finish_arch_switch().

    - IRQ cleanups by Thomas Gleixner.

    - migrate to new 'set-state' interface.

    - random small cleanups"

  • Currently the Octeon Ethernet driver hardcodes the mapping between
    interface/port and IPD port number. Since we have generic helpers for
    the very same purpose, we might as well use them instead. This prevents
    having the same information in multiple places.
