+
+/* dTSEC Events
+ * Interrupt events cause dTSEC event bits to be set. Software may poll the
+ * event register at any time to check for pending interrupts. If an event
+ * occurs and its corresponding enable bit is set in the interrupt mask
+ * register, the event also causes a hardware interrupt at the PIC.
+ * To poll for event status use the fman_dtsec_get_event() function.
+ * To configure the interrupt mask use fman_dtsec_enable_interrupt() and
+ * fman_dtsec_disable_interrupt() functions.
+ * After servicing a dTSEC interrupt use fman_dtsec_ack_event to reset the
+ * serviced event bit.
+ * The following events may be signaled by dTSEC hardware:
+ * %DTSEC_IEVENT_BABR - Babbling receive error. This bit indicates that
+ * a frame was received with length in excess of the MAC's maximum frame length
+ * register.
+ * %DTSEC_IEVENT_RXC - Receive control (pause frame) interrupt. A pause
+ * control frame was received while Rx pause frame handling is enabled.
+ * Also see fman_dtsec_handle_rx_pause().
+ * %DTSEC_IEVENT_MSRO - MIB counter overflow. The count for one of the MIB
+ * counters has exceeded the size of its register.
+ * %DTSEC_IEVENT_GTSC - Graceful transmit stop complete. Graceful stop is now
+ * complete. The transmitter is in a stopped state, in which only pause frames
+ * can be transmitted.
+ * Also see fman_dtsec_stop_tx().
+ * %DTSEC_IEVENT_BABT - Babbling transmit error. The transmitted frame length
+ * has exceeded the value in the MAC's Maximum Frame Length register.
+ * %DTSEC_IEVENT_TXC - Transmit control (pause frame) interrupt. his bit
+ * indicates that a control frame was transmitted.
+ * %DTSEC_IEVENT_TXE - Transmit error. This bit indicates that an error
+ * occurred on the transmitted channel. This bit is set whenever any transmit
+ * error occurs which causes the dTSEC to discard all or part of a frame
+ * (LC, CRL, XFUN).
+ * %DTSEC_IEVENT_LC - Late collision. This bit indicates that a collision
+ * occurred beyond the collision window (slot time) in half-duplex mode.
+ * The frame is truncated with a bad CRC and the remainder of the frame
+ * is discarded.
+ * %DTSEC_IEVENT_CRL - Collision retry limit. is bit indicates that the number
+ * of successive transmission collisions has exceeded the MAC's half-duplex
+ * register's retransmission maximum count. The frame is discarded without
+ * being transmitted and transmission of the next frame commences. This only
+ * occurs while in half-duplex mode.
+ * The number of retransmit attempts can be set in
+ * &dtsec_halfdup_cfg.retransmit before calling fman_dtsec_init().
+ * %DTSEC_IEVENT_XFUN - Transmit FIFO underrun. This bit indicates that the
+ * transmit FIFO became empty before the complete frame was transmitted.
+ * The frame is truncated with a bad CRC and the remainder of the frame is
+ * discarded.
+ * %DTSEC_IEVENT_MAG - TBD
+ * %DTSEC_IEVENT_MMRD - MII management read completion.
+ * %DTSEC_IEVENT_MMWR - MII management write completion.
+ * %DTSEC_IEVENT_GRSC - Graceful receive stop complete. It allows the user to
+ * know if the system has completed the stop and it is safe to write to receive
+ * registers (status, control or configuration registers) that are used by the
+ * system during normal operation.
+ * %DTSEC_IEVENT_TDPE - Internal data error on transmit. This bit indicates
+ * that the dTSEC has detected a parity error on its stored transmit data, which
+ * is likely to compromise the validity of recently transferred frames.
+ * %DTSEC_IEVENT_RDPE - Internal data error on receive. This bit indicates that
+ * the dTSEC has detected a parity error on its stored receive data, which is
+ * likely to compromise the validity of recently transferred frames.

+ * Transmit half-duplex flow control, under software
+ * control for 10/100-Mbps half-duplex media. If set,
+ * back pressure is applied to media by raising carrier.
+ * halfdup_retransmit:
+ * Number of retransmission attempts following a collision.
+ * If this is exceeded dTSEC aborts transmission due to
+ * excessive collisions. The standard specifies the
+ * attempt limit to be 15.
+ * halfdup_coll_window:
+ * The number of bytes of the frame during which
+ * collisions may occur. The default value of 55
+ * corresponds to the frame byte at the end of the
+ * standard 512-bit slot time window. If collisions are
+ * detected after this byte, the late collision event is
+ * asserted and transmission of current frame is aborted.
+ * rx_drop_bcast:
+ * Discard broadcast frames. If set, all broadcast frames
+ * will be discarded by dTSEC.
+ * rx_short_frm:
+ * Accept short frames. If set, dTSEC will accept frames
+ * of length 14..63 bytes.
+ * rx_len_check:
+ * Length check for received frames. If set, the MAC
+ * checks the frame's length field on receive to ensure it
+ * matches the actual data field length. This only works
+ * for received frames with length field less than 1500.
+ * No check is performed for larger frames.
+ * tx_pad_crc:
+ * Pad and append CRC. If set, the MAC pads all
+ * transmitted short frames and appends a CRC to every
+ * frame regardless of padding requirement.
+ * tx_crc:
+ * Transmission CRC enable. If set, the MAC appends a CRC
+ * to all frames. If frames presented to the MAC have a
+ * valid length and contain a valid CRC, tx_crc should be
+ * reset.
+ * This field is ignored if tx_pad_crc is set.
+ * rx_ctrl_acc:
+ * Control frame accept. If set, this overrides 802.3
+ * standard control frame behavior, and all Ethernet frames
+ * that have an ethertype of 0x8808 are treated as normal
+ * Ethernet frames and passed up to the packet interface on
+ * a DA match. Received pause control frames are passed to
+ * the packet interface only if Rx flow control is also
+ * disabled. See fman_dtsec_handle_rx_pause() function.
+ * tx_pause_time:
+ * Transmit pause time value. This pause value is used as
+ * part of the pause frame to be sent when a transmit pause
+ * frame is initiated. If set to 0 this disables
+ * transmission of pause frames.
+ * rx_preamble:
+ * Receive preamble enable. If set, the MAC recovers the
+ * received Ethernet 7-byte preamble and passes it to the
+ * packet interface at the start of each received frame.
+ * This field should be reset for internal MAC loop-back
+ * mode.
+ * tx_preamble: User defined preamble enable for transmitted frames.
+ * If set, a user-defined preamble must passed to the MAC
+ * and it is transmitted instead of the standard preamble.
+ * preamble_len:
+ * Length, in bytes, of the preamble field preceding each
+ * Ethernet start-of-frame delimiter byte. The default
+ * value of 0x7 should be used in order to guarantee
+ * reliable operation with IEEE 802.3 compliant hardware.
+ * rx_prepend:
+ * Packet alignment padding length. The specified number
+ * of bytes (1-31) of zero padding are inserted before the
+ * start of each received frame. For Ethernet, where
+ * optional preamble extraction is enabled, the padding
+ * appears before the preamble, otherwise the padding
+ * precedes the layer 2 header.
+ *
+ * This structure contains basic dTSEC configuration and must be passed to
+ * fman_dtsec_init() function. A default set of configuration values can be
+ * obtained by calling fman_dtsec_defconfig().

+ *
+ * @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().

+ * dtsec_mii_get_div() - calculates the value of the dtsec mii divider
+ * @dtsec_freq: dtsec clock frequency (in Mhz)
+ *
+ * This function calculates the dtsec mii clock divider that determines
+ * the MII MDC clock. MII MDC clock will be set to work in the range
+ * of 1.5 to 2.5Mhz
+ * The output of this function is the value of MIIMCFG[MgmtClk] which
+ * implicitly determines the divider value.
+ * Note: the dTSEC system clock is equal to 1/2 of the FMan clock.
+ * The table below which reflects dtsec_mii_get_div() functionality
+ * shows the relations among dtsec_freq, MgmtClk, actual divider
+ * and the MII frequency:
+ * dtsec freq MgmtClk div MII freq Mhz
+ * [0.....80] 1 (1/4)(1/8) [0 to 2.5]
+ * [81...120] 2 (1/6)(1/8) [1.6 to 2.5]
+ * [121..160] 3 (1/8)(1/8) [1.8 to 2.5]
+ * [161..200] 4 (1/10)(1/8) [2.0 to 2.5]
+ * [201..280] 5 (1/14)(1/8) [1.8 to 2.5]
+ * [281..400] 6 (1/20)(1/8) [1.1 to 2.5]
+ * [401..560] 7 (1/28)(1/8) [1.8 to 2.5]
+ * [560..frq] 7 (1/28)(1/8) [frq/224]
