   \class PCIEToEthernet
   \ingroup TAcq

   \brief Performs data reception (DMA) on PCI-Express and sends data over ethernet (TCP/IP network interface) 

   This class handles ethernet/network connections, reads data formatted as BRPaquet objects through PCI-Express DMA's
   and sends the received data to EthernetReader over network/ethernet, \b without ging through the memory manager 
   RAcqMemZoneMgr object.
