Version Comment
2.2  Update to EtherCAT IP Core V3.0.2/V3.00c with FX support
 RX_ER is required for EtherCAT
 Editorial changes
2.3  Renesas µPD60610/µPD60611: Auto-TX-Shift required (data sheet was
updated)
 Renesas µPD60610/µPD60611/ µPD60620/µPD60621: MI link detection and
configuration can only be enabled with certain IP Core versions
 Texas Instruments TLK105/TLK106/TLK110: MI link detection and configuration
must not be enabled
 Micrel PHYs: added notes for an internal pull-up resistor at MCLK pin
 Added note for PHYs with Enhanced link detection recommendation
 Editorial changes
