+/* struct dtsec_cfg - dTSEC configuration
+ * 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.
+ * tx_pad_crc:
+ * Pad and append CRC. If set, the MAC pads all ransmitted short frames and
+ * appends a CRC to every frame regardless of padding requirement.
+ * 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.
+ * 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
+ * init() function. A default set of configuration values can be
+ * obtained by calling set_dflts().

+ * the X550 also has a SYSTIMER register which represents residue, or
+ * subnanosecond overflow adjustments. To control clock adjustment, the TIMINCA
+ * register is used, but it is unlike the X540 and 82599 devices. TIMINCA
+ * represents units of 2^-32 nanoseconds, and uses 31 bits for this, with the
+ * high bit representing whether the adjustent is positive or negative. Every
+ * clock cycle, the X550 will add 12.5 ns + TIMINCA which can result in a range
+ * of 12 to 13 nanoseconds adjustment. Unlike the 82599 and X540 devices, the
+ * X550's clock for purposes of SYSTIME generation is constant and not dependent
+ * on the link speed.

+ *
+ * This results in a full 96 bits to represent the clock, with 32 bits for
+ * seconds, 32 bits for nanoseconds (largest value is 0d999999999 or just under
+ * 1 second) and an additional 32 bits to measure sub nanosecond adjustments for
+ * underflow of adjustments.
+ *
+ * The 32 bits of seconds for the X550 overflows every
+ * 2^32 / ( 365.25 * 24 * 60 * 60 ) = ~136 years.
+ *
+ * In order to adjust the clock frequency for the X550, the TIMINCA register is
+ * provided. This register represents a + or minus nearly 0.5 ns adjustment to
+ * the base frequency. It is measured in 2^-32 ns units, with the high bit being
+ * the sign bit. This register enables software to calculate frequency
+ * adjustments and apply them directly to the clock rate.
+ *
+ * The math for converting ppb into TIMINCA values is fairly straightforward.
+ * TIMINCA value = ( Base_Frequency * ppb ) / 1000000000ULL
+ *
+ * This assumes that ppb is never high enough to create a value bigger than
+ * TIMINCA's 31 bits can store. This is ensured by the stack. Calculating this
+ * value is also simple.
+ * Max ppb = ( Max Adjustment / Base Frequency ) / 1000000000ULL
+ *
+ * For the X550, the Max adjustment is +/- 0.5 ns, and the base frequency is
+ * 12.5 nanoseconds. This means that the Max ppb is 39999999
+ * Note: We subtract one in order to ensure no overflow, because the TIMINCA
+ * register can only hold slightly under 0.5 nanoseconds.
+ *
+ * Because TIMINCA is measured in 2^-32 ns units, we have to convert 12.5 ns
+ * into 2^-32 units, which is
+ *
+ * 12.5 * 2^32 = C80000000
