I just read about raw sockets (http://sock-raw.org/papers/sock_raw) and
when sending on raw_sockets, there wont be any fragmentation. So that
would need to be implemented in sr as well.
Is the performance gain really worth the effort? I wonder why
constructing of IP/UDP headers in sr is faster than having it done in
the kernel.
another interesting point is if the raw socket receives the packet
before or after iptables filtering.

Lovely.
Do you plan to export this functionality to the script? e.g. if
force_send_socket() does not find the forced UDP socket, it uses a
raw socket?
Not exactly, I plan to use it as a replacement for udp sockets (higher
performance on send on linux) and in the future for handling icmp.
The force_send_socket() stuff it's a good idea.
