EtherCAT master TODO
$Id$
-------------------------------------------------------------------------------
* Release 1.3:
- Dynamic creation of EoE handlers.
* Future features:
- Interface/buffers for asynchronous domain IO.
- Distributed clocks.
- Read dynamic PDO mapping from SDO dictionary (see can-cia.org: cia301ds4).
- Redundancy with 2 network adapters.
* Smaller issues:
- Clear sync managers in INIT.
- Simplify FSMs with <state>_enter() functions.
- Output intermediate results during lsec.
- State change FSM: Follow spontaneous state changes.
- Read out CRC counters.
- Calculate expected working counter for domains.
- Optimize alignment of process data.
- Evaluate EEPROM contents after writing.
- SDO dictionary fetching in operation mode.
- SDO write access in sysfs.
- Configure slave ports to automatically open on link detection.
- Calculate cycle time of operation state machine.
* Less important issues:
- Implement all EtherCAT datagram types.
- File access over EtherCAT (FoE).
- Allow VLAN tagging.
- Determine number of frames the NIC can handle.
