yes，i don't want to use an old version either.but there has been a problem that I can't resolve . I made a capture program to collecte datas which are sent from an fpga . There are several receive threads in the program, each of threads accesses a global netcard port in tern. In order to verify the performace ,it just do the least thing In the receive thread---it just count the amount of Ethernet frames that it receive. But when the fpga sending rate increases,especially above 500Mbps, it sometimes loss packets. My question is, is it possible to totally avoid packets loss by optimism the code? I want to collect datas on the speed 614Mbps without packet loss. My workstations features with 2 Xeon CPU (each has 4core), 1 G onboard netcard. <br>
