* Issues for release 1.3.0:

    10

  - Take broadcast MAC address to register the first ethernet device.

    11

  - Limit EEPROM reading.

    12

  - Implement ecrt_get_slave() with integer argument as ring position.

    14

    15

* Future features:

    16

  - Interface/buffers for asynchronous domain IO.

    17

  - Distributed clocks.

    19

  - Redundancy with 2 network adapters.

    22

    23

* Smaller issues:

    24

  - Clear sync managers in INIT.

    25

  - Simplify FSMs with <state>_enter() functions.

    26

  - Output intermediate results during lsec.

    27

  - State change FSM: Follow spontaneous state changes.

    28

  - Read out CRC counters.

    29

  - Calculate expected working counter for domains.

    30

  - Optimize alignment of process data.

    31

  - Evaluate EEPROM contents after writing.

    32

  - SDO write access in sysfs.

    33

  - Configure slave ports to automatically open on link detection.

    34

  - Calculate cycle time of operation state machine.

    35

  - Locking for serveral slave variables for sysfs access.

    36

  - Interrupt master state machines state scan for other jobs.

    37

  - Master state machine, slave configuration: Do not check every slave on

    38

    a cycle.

    39

  - Do only execute one EoE handler per EoE cycle.

    40

    41

* Less important issues:

    42

  - Implement all EtherCAT datagram types.

    43

  - File access over EtherCAT (FoE).

    44

  - Allow VLAN tagging.

    45

  - Determine number of frames the NIC can handle.
