  • ec3a2207c   staging: octeon-ethernet: Move PHY activation to .ndo_open(). ... Browse Code »

    This prevents PHY not found types of errors for PHY drivers that are
    probed after the Ethernet driver is probed, because the ifconfig UP is
    done from userspace after all drivers have been probed.

    Also avoid the cvmx-helper-board.c PHY code if a real PHY driver is
    present, this allows a bootloader supplied device tree to specify the
    PHY information rather than having to modify the code for each
    different board.

  • 7cc4fa1e5   staging: octeon-ethernet: rgmii: enable interrupts that we can handle ... Browse Code »

    Enable only those interrupts that we can handle & acknowledge in the
    interrupt handler.

    At least on EdgeRouter Lite, the hardware may occasionally interrupt with
    some error condition when the physical link status changes frequently.
    Since the interrupt condition is not acked properly, this leads to the
    following warning and the IRQ gets disabled completely:

  • f696a1083   Staging: octeon-ethernet: Convert to use net_device_ops. ... Browse Code »

    Convert the driver to use net_device_ops as it is now mandatory.

    Also compensate for the removal of struct sk_buff's dst field.

    The changes are mostly mechanical, the content of ethernet-common.c
    was moved to ethernet.c and ethernet-common.{c,h} are removed.

  • 80ff0fd3a   Staging: Add octeon-ethernet driver files. ... Browse Code »

    The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui
    ports present on the Cavium OCTEON family of SOCs. These SOCs are
    multi-core mips64 processors with existing support over in arch/mips.

    The driver files can be categorized into three basic groups:

    1) Register definitions, these are named cvmx-*-defs.h

    2) Main driver code, these have names that don't start cvmx-.

    3) Interface specific functions and other utility code, names starting
    with cvmx-
