* Future features:
- Distributed clocks.
- Redundancy with 2 network adapters.
- Mailbox handler
- Support slaves, that don't support the LRW datagram, only LRD/LWR.
- PDO reading in IDLE mode.
- Replace Sysfs interface with cdev and user space program.
- Interface/buffers for asynchronous domain IO.
- Remove ecdb.h and let lsec output pdo information 'cut-and-pasteable' for
applications.
- SDO access via realtime interface.
- Scanning shall include reading the PDO mapping via CoE.
Version 1.4.0:
* Smaller issues:
- Datagram debugging flag.
- Clear sync managers in INIT.
- Simplify FSMs with <state>_enter() functions.
- Output intermediate results during lsec.
- Read out CRC counters.
- Calculate expected working counter for domains.
- Optimize alignment of process data.
- Evaluate EEPROM contents after writing.
- SDO write access in sysfs.
- Configure slave ports to automatically open on link detection.
- Calculate cycle time of operation state machine.
- Locking for serveral slave variables for sysfs access.
- Interrupt master state machines state scan for other jobs.
- Master state machine, slave configuration: Do not check every slave on
a cycle.
- Only execute one EoE handler per EoE cycle.
* Realtime interface changes:
- PDO configuration.
- SDO access.
- Replace process data pointers with offset.
- External memory for domains.
* Mailbox handler
* Read PDO mapping via CoE during bus scan.
* SDO write access in sysfs.
* Remove get_cycles() calls and references to cpu_khz to increase
portability.
* Remove ecdb.h and let lsec output PDO information 'cut-and-pastable' for
applications.
* Update documentation.
* Less important issues:
- Implement all EtherCAT datagram types.
- File access over EtherCAT (FoE).
- Allow VLAN tagging.
- Determine number of frames, the NIC can handle.
Future issues:
* Move slave handlers and state machines, etc. into a user space daemon.
- Step 1: Replace Sysfs interface with cdev and a user space program
to replace lsec.
- Step 2: Move kernel threads to user space daemon with a TCP interface
replacing the cdev.
