/**
   Create an EtherCAT hardware interface which uses UDP formatted messages.  This is the only type of EtherCAT interface that can
   be used under Windows without installing special drivers.

   The low level EtherCAT protocol normally does not use an IP address, however since this driver transmits EtherCAT packets over 
   UDP/IP, the Ethernet interface used with this driver must have a valid IP address assigned.  In addition, the network mask 
   associated with the Ethernet interface should be defined in such a way that no other network interface on the same PC is a member
   of the same network.  That is, if multiple interfaces are installed then they should be allocated to seperate networks.

   i.e. ( IP1 & mask1 ) != (IP2 & mask2) 
      where IP1 and mask1 are the IP address and net mask of the first interface, and IP2 and mask2 are for the second interface.

   For example, the following two interfaces are on different networks:
      IP: 192.168.1.1   mask: 255.255.255.0
      IP: 192.168.2.1   mask: 255.255.255.0

   but the following two interfaces are on the same network:
      IP: 192.168.1.1   mask: 255.255.255.0
      IP: 192.168.1.2   mask: 255.255.255.0

   This is important because this drive has no direct control of which interface the packets are being sent out.  This is entirely
   controlled by the upper layer routing algorithms in the windows network stack.

   The name parameter passed to this function can be used to identify which interface this object should bind to.  It can take 
   any of the following forms:

   - If not specified, then the first valid interface found will be used.  This is useful if there's only one interface on the PC.

   - If of the form; eth0, eth1, eth2, etc, then the nth valid interface will be used.

   - For more control, the IP address of the desired interface can be passed.  This should be sent as a string in dotted decimal
     notation.  For example: "192.168.1.1"

   @param name Used to identify the Ethernet interface as described above.
