Choose behavior of scalable listening sockets when using EF_SCALABLE_FILTERS

• 0 – Listening sockets bound to a local address configured on the scalable interface use the scalable filter (default). Connections on other interfaces are not accelerated.
• 1 – Listening sockets bound to a local address configured on the scalable interface use the scalable filter. Connections on other interfaces including loopback are refused.

  This mode avoids kernel scalability issues with large numbers of listen sockets.
