fp@776: Version 1.4.0:
fp@547: 
fp@776: * Realtime interface changes:
fp@776:     - PDO configuration.
fp@776:     - SDO access.
fp@776:     - Replace process data pointers with offset.
fp@776:     - External memory for domains.
fp@776: * Mailbox handler
fp@776: * Read PDO mapping via CoE during bus scan.
fp@776: * SDO write access in sysfs.
fp@776: * Remove get_cycles() calls and references to cpu_khz to increase
fp@776:   portability.
fp@776: * Remove ecdb.h and let lsec output PDO information 'cut-and-pastable' for
fp@776:   applications.
fp@776: * Update documentation.
fp@547: 
fp@776: Future issues:
fp@776: 
fp@776: * Move slave handlers and state machines, etc. into a user space daemon.
fp@776:     - Step 1: Replace Sysfs interface with cdev and a user space program
fp@776:               to replace lsec.
fp@776:     - Step 2: Move kernel threads to user space daemon with a TCP interface
fp@776:               replacing the cdev.
fp@776: * Distributed clocks.
fp@776: * Redundancy with 2 network adapters.
fp@776: * Support slaves, that don't support the LRW datagram, only LRD/LWR.
fp@776: * PDO reading in IDLE mode.
fp@776: * Interface/buffers for asynchronous domain IO.
fp@776: 
fp@776: Smaller issues:
fp@776: 
fp@776: * Datagram debugging flag.
fp@776: * Clear sync managers in INIT.
fp@776: * Simplify FSMs with <state>_enter() functions.
fp@776: * Read out CRC counters.
fp@776: * Calculate expected working counter for domains.
fp@776: * Optimize alignment of process data.
fp@776: * Evaluate EEPROM contents after writing.
fp@776: * Configure slave ports to automatically open on link detection.
fp@776: * Calculate cycle time of operation state machine.
fp@776: * Locking for serveral slave variables for sysfs access.
fp@776: * Interrupt master state machines state scan for other jobs.
fp@776: * Master state machine, slave configuration: Do not check every slave on
fp@776:   a cycle.
fp@776: * Only execute one EoE handler per EoE cycle.
fp@776: 
fp@776: Less important issues:
fp@776: 
fp@776: * Implement all EtherCAT datagram types.
fp@776: * File access over EtherCAT (FoE).
fp@776: * Allow VLAN tagging.
fp@776: * Determine number of frames, the NIC can handle.
