Hello Gilad,
This patches are good. I want to check one thing about it.
Multi threaded app for raw sockets can reads the same packet in all
thread at
the same time if each thread reads from different sockets but source
address is the same.
To avoid that I did:
527a305 single raw socket for all threads
In case with mmap/fanout each thread binded to different cpus will
receive packets fanout-ed
by the kernel. So packets to that threads will not duplicate.
In your patch you defined fanout for case if it's not supported. So that
fanout will not work.
Can you please check that threads do not receive the same packets?
Thank you,
Maxim.

The following patch set provides backward compatability wrappers
for defines and functions needed to get ODP built and examples
run on older systems without sendmmsg and PACKET_FANOUT support
in either kernel or libc.
Specifically, with this patch set I get ODP built and examples
run on a CentOS 6.5 host, where the build was previously failing.
The patches have zero effect (build or run time) on systems where
ODP was building before.
Since ODP now builds and run on CentOS 6.5 with kernel version 2.6.x,
I also dropped the 3.x dependency.
Only minimal testing (I ran a couple of the examples) were done for
newly supported systems.
