EtherCAT master TODO

vim700: spelllang=en spell

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

Version 1.5.0:

* Distributed clocks:
    - Check 32/64 bit operations.
    - Use vendor correction factors when calculating transmission delays.
    - Skip setting system time offset when application detached.
    - How to use the SYNC1 shift time?
    - Do not output graph, if topology calculation failed.
    - Set the "Cyclic Generation Start Time" based on the slave's
      "System Time" register instead of using the application time.
    - Check if register 0x0980 is working, to avoid clearing it when
      configuring.
* Remove byte-swapping functions from user space.
* Implement 'ethercat foe_read --output-file ...'.
* Use ec_datagram_zero() where possible.
* Fix arguments of reg_read.
* Number layout for reg_read.
* Show Record / Array / List type of SDOs.
* Finish library implementation.
* Rescan command.
* Override sync manager size?
* Check force_config flag before error.
* Remove allow_scanning flag.
* Check for ioctl() interface version.
* Improve application-triggered SDO transfers by moving the state machine into
  the SDO handlers.
* Document ec_fsm_foe members.
* Test KBUILD_EXTRA_SYMBOLS.
* Remove default buffer size in SDO upload.
* Check for Enable SDO Complete Access flag.
* Implement CompleteAccess for command-line tool.
* Implement CompleteAccess for SDO uploads.
* Implement identifier parameter for cstruct command.
* Implement sync delimiter for cstruct command.
* Change SDO index at runtime for SDO request.
* Implement ecrt_slave_config_request_state().
* Output skipped datagrams again.
* Output warning on unmatched slave configuration.
* ec_direction_t default
* Send_ext context warn
* XML hex
* r8169

Future issues:

* Mailbox protocol handlers.
* Mailbox state machine using toggle bits.
* External memory for SDO transfers.
* C++ implementation of the library.
* Bus simulator interface.
* Move master threads, slave handlers and state machines into a user
  space daemon.
* Allow master requesting when in ORPHANED phase
* 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).
* ethercat tool:
    - Data type abbreviations.
    - Add a -n (numeric) switch.
	- Check for unwanted options.
* Simplify master fsm by introducing a common request state to handle external
  requests (replace write_sii, sdo_request, etc).

Smaller issues:

* Read out CRC counters.
* Configure slave ports to automatically open on link detection.
* Fix datagram errors on application loading/unloading.

Less important issues:

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