[Ntop-misc] n2disk/disk2n: Problem with PF_RING ZC

2017-05-17 Thread Lüthi Marcel FUB 
Hello.

I want to maximize the performance for n2disk/disk2n and use PF_RING ZC.
PF_RING only is working as expected, but this doesn't:

[root@myhost]# pfcount -i zc:eno1
pfring_open error [No such device] (pf_ring not loaded or interface zc:eno1 is 
down ?)

[root@myhost]# pfsend -i zc:eno1
Sending packets on zc:eno1
pfring_open error [No such device] (pf_ring not loaded or interface zc:eno1 is 
down ?)

The kernel modules seem to be loaded:
