When socket caching is enabled, (i.e. when EF_SOCKET_CACHE_MAX > 0), this sets a further limit on the size of the cache for each socket.

• If set to -1 in Onload 201805 onwards, or to 0 in earlier versions, no limit is set beyond the global limit specified by EF_SOCKET_CACHE_MAX.

  This behavior is the default.

• If set to 0 in Onload 201805 onwards, no accepted sockets will be cached for any listening sockets. This allows active-open socket caching to be enabled without also enabling passive-open socket caching.
