Hello everyone,
I'm in need of accessing the tsval value of the options field in the
tcp header... i've been checking the tcp.h and did not find anything
that helped me.
Does any body know how to do it?
Best regards

He could be useful to add a build and check on a big-endian system.
What do you think about it?
I would

I have created a repo with a cloned copy of the pcap repository
with netmap support:
https://code.google.com/p/netmap-libpcap
With that, you can easily have tcpdump (and any libpcap application)
process 10-15Mpps with a single thread through NICs in netmap mode

I did not test, but it seems promising :

So, basically if we use a device name like netmap: or vale,
then we would get support for it. Are there dependancies that would
piss off distros that we should worry about? You say that we need netmap,
but I don't see where in the build it references some new library.
Fork, and push your

At runtime, netmap only uses open(), ioctl(), mmap() and poll().

Right, thanks !

Also, when a port is in netmap mode is temporarily disconnected from
the host stack, so you want to be careful on where you use it.
The monitoring folks (bro, suricata...) will probably love this
feature but for others it might be more

I think what Michael means is that if we include net/netmap.h and
net/netmap_user.h in the libpcap distribution, we can have the support
always compiled in and postpone the decision at compile time.

Yes - some tests fail if the full set of support libraries weren't available
when tcpdump was built.
Perhaps we want to suppress some tests if we don't have
