/**
 * struct tgec_cfg - TGEC configuration
 *
 * @rx_error_discard:    Receive Erroneous Frame Discard Enable. When set to 1
 *            any frame received with an error is discarded in the
 *            Core and not forwarded to the Client interface.
 *            When set to 0 (Reset value), erroneous Frames are
 *            forwarded to the Client interface with ff_rx_err
 *            asserted.
 * @pause_ignore:    Ignore Pause Frame Quanta. If set to 1 received pause
 *            frames are ignored by the MAC. When set to 0
 *            (Reset value) the transmit process is stopped for the
 *            amount of time specified in the pause quanta received
 *            within a pause frame.
 * @pause_forward_enable:
 *            Terminate / Forward Pause Frames. If set to 1 pause
 *            frames are forwarded to the user application. When set
 *            to 0 (Reset value) pause frames are terminated and
 *            discarded within the MAC.
 * @no_length_check_enable:
 *            Payload Length Check Disable. When set to 0
 *            (Reset value), the Core checks the frame's payload
 *            length with the Frame Length/Type field, when set to 1
 *            the payload length check is disabled.
 * @cmd_frame_enable:    Enables reception of all command frames. When set to 1
 *            all Command Frames are accepted, when set to 0
 *            (Reset Value) only Pause Frames are accepted and all
 *            other Command Frames are rejected.
 * @send_idle_enable:    Force Idle Generation. When set to 1, the MAC
 *            permanently sends XGMII Idle sequences even when faults
 *            are received.
 * @wan_mode_enable:    WAN Mode Enable. Sets WAN mode (1) or LAN mode
 *            (0, default) of operation.
 * @promiscuous_mode_enable:
 *            Enables MAC promiscuous operation. When set to 1, all
 *            frames are received without any MAC address filtering,
 *            when set to 0 (Reset value) Unicast Frames with a
 *            destination address not matching the Core MAC Address
 *            (MAC Address programmed in Registers MAC_ADDR_0 and
 *            MAC_ADDR_1 or the MAC address programmed in Registers
 *            MAC_ADDR_2 and MAC_ADDR_3) are rejected.
 * @tx_addr_ins_enable:    Set Source MAC Address on Transmit. If set to 1 the
 *            MAC overwrites the source MAC address received from the
 *            Client Interface with one of the MAC addresses. If set
 *            to 0 (Reset value), the source MAC address from the
 *            Client Interface is transmitted unmodified to the line.
 * @loopback_enable:    PHY Interface Loopback. When set to 1, the signal
 *            loop_ena is set to '1', when set to 0 (Reset value)
 *            the signal loop_ena is set to 0.
 * @lgth_check_nostdr:    The Core interprets the Length/Type field differently
 *            depending on the value of this Bit
 * @time_stamp_enable:    This bit selects between enabling and disabling the
 *            IEEE 1588 functionality. 1: IEEE 1588 is enabled
 *            0: IEEE 1588 is disabled
 * @max_frame_length:    Maximum supported received frame length.
 *            The 10GEC MAC supports reception of any frame size up
 *            to 16,352 bytes (0x3FE0). Typical settings are
 *            0x05EE (1,518 bytes) for standard frames.
 *            Default setting is 0x0600 (1,536 bytes).
 *            Received frames that exceed this stated maximum
 *            are truncated.
 * @pause_quant:    Pause quanta value used with transmitted pause frames.
 *            Each quanta represents a 512 bit-times.
 * @tx_ipg_length:    Transmit Inter-Packet-Gap (IPG) value. A 6-bit value:
 *            Depending on LAN or WAN mode of operation the value has
 *            the following meaning: - LAN Mode: Number of octets in
 *            steps of 4. Valid values are 8, 12, 16, ... 100. DIC is
 *            fully supported (see 10.6.1 page 49) for any setting. A
 *            default of 12 (reset value) must be set to conform to
 *            IEEE802.3ae. Warning: When set to 8, PCS layers may not
 *            be able to perform clock rate compensation. - WAN Mode:
 *            Stretch factor. Valid values are 4..15. The stretch
 *            factor is calculated as (value+1)*8. A default of 12
 *            (reset value) must be set to conform to IEEE 802.3ae
 *            (i.e. 13*8=104). A larger value shrinks the IPG
 *            (increasing bandwidth).
 *
 * This structure contains basic TGEC configuration and must be passed to
 * fman_tgec_init() function.  A default set of configuration values can be
 * obtained by calling fman_tgec_defconfig().
