    net/mlx4_en: Add HW timestamping (TS) support · ec693d47
    Amir Vadai authored
    The patch allows to enable/disable HW timestamping for incoming and/or
    outgoing packets. It adds and initializes all structs and callbacks
    needed by kernel TS API.
    To enable/disable HW timestamping appropriate ioctl should be used.
    Currently HWTSTAMP_FILTER_ALL/NONE and HWTSAMP_TX_ON/OFF only are
    supported.
    When enabling TS on receive flow - VLAN stripping will be disabled.
    Also were made all relevant changes in RX/TX flows to consider TS request
    and plant HW timestamps into relevant structures.
    mlx4_ib was fixed to compile with new mlx4_cq_alloc() signature.
