EtherCAT master TODO

$Id$

-------------------------------------------------------------------------------

Future issues:

* Distributed clocks.
* Implement user space realtime interface via cdev.
* Move master threads, slave handlers and state machines into a user
  space daemon.
* Allow master requesting when in ORPHANED phase
* Mailbox protocol handlers.
* Mailbox state machine using toggle bits.
* Mailbox gateway.
* Separate CoE debugging.
* Evaluate EEPROM contents after writing.
* Optimize alignment of process data.
* Redundancy with 2 network adapters.
* Interface/buffers for asynchronous domain IO.
* Make scanning and configuration run parallel (each).
* File access over EtherCAT (FoE).
* Vendor-specific over EtherCAT (VoE).
* ethercat tool:
    - Data type abbreviations.
    - Add a -n (numeric) switch.
	- Check for unwanted options.
* Segmented Sdo downloads.

Smaller issues:

* Stop master thread at ecrt_master_request() to get rid of allow_* flags?
* Evaluate SII Size field (0x003E) to determine maximum SII memory size.
* Clear sync managers in INIT.
* Read out CRC counters.
* Configure slave ports to automatically open on link detection.
* Only execute one EoE handler per EoE cycle.
* Fix datagram errors on application loading/unloading.

Less important issues:

* Allow VLAN tagging.
* Determine number of frames, the NIC can handle.
