Hello, I solved, the original netmap can not take the initiative to set the promiscuous, thank you
I found a problem that I used Libpcap capture, like CPU load is not high,
But I use netmap+libpcap CPU load is very high, is this normal? Thank you

Luigi Rizzo Hello, thank you for your selfless contributions netmap the fast packet I/O framework,
I have a little problem now, the thing is such, do not know if you can help me to have a look? Thank you
I do the test in the Linux kernel version 3.0.80 below, I discovered that netmap cannot receive packets, machine I is the following
I use the lsmod command output, that I should have been loaded with netmap_lin.ko and e1000e.ko
[root at localhost ~]# lsmod
Module Size Used by
e1000e 20996 0
netmap_lin 253984 1 e1000e
Then I use tcpdump -i eth1 to capture can normally receive all packets
But I tcpdump -i netmap:eth1
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
[root at centos examples]# tcpdump -i netmap:eth1
Pcap_netmap_activate device netmap:eth1 priv 0x1bac600 FD 3 ports 0..0
Pcap_netmap_ioctl eth1 IOCTL 0x8913 returns 0
Pcap_netmap_ioctl eth1 IOCTL 0x8914 returns 0
Tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

I don't know Is it right? E1000e the driver where I didn't use to bag is not normal
But I'm also a machine this machine is installed above the driver is E1000 centos6.2 Linux kernel version is 3.0.80
In this machine above I can use the normal netmap bag.
Thank you, sincerely waiting for your reply, thank you
