Hello,
we have set up pf_ring correctly on a RHEL 6.1 system.
We have loaded two pf_ring aware drivers: igb and cxgb4
All the applications works well with the interfaces managed by the igb
driver.
Instead we cannot receive packets from the interfaces managed by cxgb4.
pf_count and tcpdump for these interfaces show like 1 pkt per 2
seconds....and tcpdump can not even show what kind of packets are.
ifconfig instead is showing a lot of traffic reaching the NICs.
We are using pf_ring stable 4.7.3
We have reproduced this problem both in kernel 2.6.32.46 and 2.6.35.14
The compile process goes well and dmesg does not report errors when
loads the module.
Compile output (with some warnings)

What kernel is needed for cxgb4?
Also if we run 'make install' in the cxgb4 the process does not complete
for missing files.
Any suggestions i welcome.
Thank you,
Enrico.
