Hi everyone,
I have been testing pf_ring-aware drivers on performance and find this
problem. tx capture works normal.
I have been sending packets with pfsend either on local machine and from
the remote with this command:
$./pfsend -n 10000 -i eth0
capture was saying that there were no packets captured:
$./pfcount -i eth0 -e 1
I have used latest pf_ring (5.4.6-r5751) and driver (e1000e-2.0.1). There
was deffenitly some other constant traffic on this device (checked with
tcpdump). At first i compiled and loaded e1000e then pf_ring with
transparent_mode=1. Here is some info on my machine:
$cat /proc/net/pf_ring/info
