# From the OpenOnload website, http://www.openonload.org/ :
#   ``OpenOnload(r) is a high performance network stack from Solarflare that
#   dramatically reduces latency and cpu utilisation, and increases message rate
#   and bandwidth.  OpenOnload runs on Linux and supports TCP/UDP/IP network
#   protocols with the standard BSD sockets API, and requires no modifications
#   to applications to use. It achieves performance improvements in part by
#   performing network processing at user-level, bypassing the OS kernel
#   entirely on the data path. Networking performance is improved without
#   sacrificing the security and multiplexing functions that the OS kernel
#   normally provides.'' (10/3/2013)
