Important things to do:
* Add Kobjects in constructors.
* Read AL Status Code with AL Control Response (if possible?)
* Coupling of EoE handlers before configuring slaves.
(avoiding duplicate configuration)
* SysFS interface
- Add secondary slave address
- Add SDO dictionary
* Implement all EtherCAT commands
* Determine number of frames the NIC can handle
* Implement eepro100 driver
* Progress bar in ecrt.

Not-so-important things to do:
* Calculate bus topology
* File access over EtherCAT (FoE)
* Allow VLAN tagging
