kernel 3.9 / new networking options for RADOS

[Kasper Dieter <dieter.kasper@ts.fujitsu.com>]

What are the options for RADOS to make use of the new
networking feature in Kernel 3.9 ?

TCP and UDP sockets now support a SO_REUSEPORT option that allows multiple
sockets to listen on the same port. This enables, for example, multiple
web server processes or threads to open individual sockets to listen
on port 80; any connections that come in on this port will be evenly
distributed across the sockets by the kernel.

This approach aims to improve the way workloads are distributed across the
available processor cores. (...) this extension can help avoid bottlenecks
that appear in certain situations when only one thread accepts new
connections and then distributes them across other threads. (...)
