254  * struct tgec_cfg - TGEC configuration
255  *
256  * @rx_error_discard:    Receive Erroneous Frame Discard Enable. When set to 1
257  *            any frame received with an error is discarded in the
258  *            Core and not forwarded to the Client interface.
259  *            When set to 0 (Reset value), erroneous Frames are
260  *            forwarded to the Client interface with ff_rx_err
261  *            asserted.
262  * @pause_ignore:    Ignore Pause Frame Quanta. If set to 1 received pause
263  *            frames are ignored by the MAC. When set to 0
264  *            (Reset value) the transmit process is stopped for the
265  *            amount of time specified in the pause quanta received
266  *            within a pause frame.
267  * @pause_forward_enable:
268  *            Terminate / Forward Pause Frames. If set to 1 pause
269  *            frames are forwarded to the user application. When set
270  *            to 0 (Reset value) pause frames are terminated and
271  *            discarded within the MAC.
272  * @no_length_check_enable:
273  *            Payload Length Check Disable. When set to 0
274  *            (Reset value), the Core checks the frame's payload
275  *            length with the Frame Length/Type field, when set to 1
276  *            the payload length check is disabled.
277  * @cmd_frame_enable:    Enables reception of all command frames. When set to 1
278  *            all Command Frames are accepted, when set to 0
279  *            (Reset Value) only Pause Frames are accepted and all
280  *            other Command Frames are rejected.
281  * @send_idle_enable:    Force Idle Generation. When set to 1, the MAC
282  *            permanently sends XGMII Idle sequences even when faults
283  *            are received.
284  * @wan_mode_enable:    WAN Mode Enable. Sets WAN mode (1) or LAN mode
285  *            (0, default) of operation.
286  * @promiscuous_mode_enable:
287  *            Enables MAC promiscuous operation. When set to 1, all
288  *            frames are received without any MAC address filtering,
289  *            when set to 0 (Reset value) Unicast Frames with a
290  *            destination address not matching the Core MAC Address
291  *            (MAC Address programmed in Registers MAC_ADDR_0 and
292  *            MAC_ADDR_1 or the MAC address programmed in Registers
293  *            MAC_ADDR_2 and MAC_ADDR_3) are rejected.
294  * @tx_addr_ins_enable:    Set Source MAC Address on Transmit. If set to 1 the
295  *            MAC overwrites the source MAC address received from the
296  *            Client Interface with one of the MAC addresses. If set
297  *            to 0 (Reset value), the source MAC address from the
298  *            Client Interface is transmitted unmodified to the line.
299  * @loopback_enable:    PHY Interface Loopback. When set to 1, the signal
300  *            loop_ena is set to '1', when set to 0 (Reset value)
301  *            the signal loop_ena is set to 0.
302  * @lgth_check_nostdr:    The Core interprets the Length/Type field differently
303  *            depending on the value of this Bit
304  * @time_stamp_enable:    This bit selects between enabling and disabling the
305  *            IEEE 1588 functionality. 1: IEEE 1588 is enabled
306  *            0: IEEE 1588 is disabled
307  * @max_frame_length:    Maximum supported received frame length.
308  *            The 10GEC MAC supports reception of any frame size up
309  *            to 16,352 bytes (0x3FE0). Typical settings are
310  *            0x05EE (1,518 bytes) for standard frames.
311  *            Default setting is 0x0600 (1,536 bytes).
312  *            Received frames that exceed this stated maximum
313  *            are truncated.
314  * @pause_quant:    Pause quanta value used with transmitted pause frames.
315  *            Each quanta represents a 512 bit-times.
316  * @tx_ipg_length:    Transmit Inter-Packet-Gap (IPG) value. A 6-bit value:
317  *            Depending on LAN or WAN mode of operation the value has
318  *            the following meaning: - LAN Mode: Number of octets in
319  *            steps of 4. Valid values are 8, 12, 16, ... 100. DIC is
320  *            fully supported (see 10.6.1 page 49) for any setting. A
321  *            default of 12 (reset value) must be set to conform to
