Everything works finer after switching virtual consoles on the client and "ifconfig'ing" the fxp1 as full-duplex, from the holographic shell. What is even more startling is that the same fxp1 is correctly set up as full duplex with the 4.8-RELEASE install kernel (from the same boot server, with the same setup for its NIC : I've installed two tftpboot directories so as to select which release is loaded via PXE). On monday , I'll try to wire the server em NIC as half-duplex to see wether the client fxp1 has a better throughput (afterwards, I'll try and look for differences in the 4.8 and 5.1 fxp drivers). Happy hacking TfH
