- * enum cip_flags - describes details of the streaming protocol
- * @CIP_NONBLOCKING: In non-blocking mode, each packet contains
- *	sample_rate/8000 samples, with rounding up or down to adjust
- *	for clock skew and left-over fractional samples.  This should
- *	be used if supported by the device.
- * @CIP_BLOCKING: In blocking mode, each packet contains either zero or
- *	SYT_INTERVAL samples, with these two types alternating so that
- *	the overall sample rate comes out right.
- * @CIP_SYNC_TO_DEVICE: In sync to device mode, time stamp in out packets is
- *	generated by in packets. Defaultly this driver generates timestamp.
- * @CIP_EMPTY_WITH_TAG0: Only for in-stream. Empty in-packets have TAG0.
- * @CIP_DBC_IS_END_EVENT: Only for in-stream. The value of dbc in an in-packet
- *	corresponds to the end of event in the packet. Out of IEC 61883.
- * @CIP_WRONG_DBS: Only for in-stream. The value of dbs is wrong in in-packets.
- *	The value of data_block_quadlets is used instead of reported value.
- * @CIP_SKIP_DBC_ZERO_CHECK: Only for in-stream.  Packets with zero in dbc is
- *	skipped for detecting discontinuity.
- * @CIP_SKIP_INIT_DBC_CHECK: Only for in-stream. The value of dbc in first
- *	packet is not continuous from an initial value.
- * @CIP_EMPTY_HAS_WRONG_DBC: Only for in-stream. The value of dbc in empty
- *	packet is wrong but the others are correct.
- * @CIP_JUMBO_PAYLOAD: Only for in-stream. The number of data blocks in an
- *	packet is larger than IEC 61883-6 defines. Current implementation
- *	allows 5 times as large as IEC 61883-6 defines.

- * enum cip_sfc - supported Sampling Frequency Codes (SFCs)
- * @CIP_SFC_32000:   32,000 data blocks
- * @CIP_SFC_44100:   44,100 data blocks
- * @CIP_SFC_48000:   48,000 data blocks

- * @CIP_SFC_192000: 192,000 data blocks
- * @CIP_SFC_COUNT: the number of supported SFCs
- *
- * These values are used to show nominal Sampling Frequency Code in
- * Format Dependent Field (FDF) of AMDTP packet header. In IEC 61883-6:2002,
- * this code means the number of events per second. Actually the code
- * represents the number of data blocks transferred per second in an AMDTP
- * stream.
- *
- * In IEC 61883-6:2005, some extensions were added to support more types of
- * data such as 'One Bit LInear Audio', therefore the meaning of SFC became
- * different depending on the types.
- *
- * Currently our implementation is compatible with IEC 61883-6:2002.
