Different/Same queue used for promiscuous capture on ethernet ?

Hi Everyone, I am doing a packet capture on 480 MHz router on ethernet interface using pcap and see packet drops for anything greater than 50-60 Mbps. My question is following : Does pcap (and hence the kernel) create a new queue for all the packets in the promiscuous or is it collecting all packets in the same/default queue attached to the interface eth0 ? I am asking above question because I want to know if the router starts dropping packets destined to itself because of this promiscuous mode capture? I think 480 MHz is quite good processor, it is hard for me to believe that there is packet drops in queues. Router used : http://support.netgear.com/product/WNDR3700v2 Thanks, Abhinav _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
