This driver adds support for EtherCAT master module located on CCAT FPGA found on Beckhoff CX series industrail PCs. The driver exposes EtherCAT master as an ethernet interface.
EtherCAT is a filedbus protocol defined on top of ethernet and Beckhoff CX5020 PCs come with built-in EtherCAT master module located on a FPGA, which in turn is connected to a PCI bus.
