32 \brief Performs data reception (DMA) on PCI-Express and sends data over ethernet (TCP/IP network interface)
33
34 This class handles ethernet/network connections, reads data formatted as BRPaquet objects through PCI-Express DMA's
35 and sends the received data to EthernetReader over network/ethernet, \b without ging through the memory manager
36 RAcqMemZoneMgr object.

456 connections (data reception from several PCIEToEthernet senders) and can optionnaly synchronize data using the
457 FrameCounter.
