Applied to dpdk-next-virtio/master with below commit message

------------------------------------------------------------
More precisely, do not generate a SIGPIPE signal if the peer
has closed the connection. Otherwise, it will terminate the
process by default. As a library, we should avoid terminating
the application process when error happens and just need to
return with an error.
------------------------------------------------------------

Thanks,
Maxime
