  - isReusePort
```
public boolean isReusePort()
```
    Returns true if the SO_REUSEPORT option is set.
  - setReusePort
```
public IOUringServerSocketChannelConfig setReusePort(boolean reusePort)
```
    Set the SO_REUSEPORT option on the underlying Channel. This will allow to bind multiple ServerSocketChannels to the same port and so accept connections with multiple threads. Be aware this method needs be called before ChannelOutboundInvoker.bind(java.net.SocketAddress) to have any affect.
  - isFreeBind
```
public boolean isFreeBind()
```
    Returns true if IP_FREEBIND is enabled, false otherwise.
  - setFreeBind
```
public IOUringServerSocketChannelConfig setFreeBind(boolean freeBind)
```
    If true is used IP_FREEBIND is enabled, false for disable it. Default is disabled.
  - isIpTransparent
```
public boolean isIpTransparent()
```
    Returns true if IP_TRANSPARENT is enabled, false otherwise.
  - setIpTransparent
```
public IOUringServerSocketChannelConfig setIpTransparent(boolean transparent)
```
    If true is used IP_TRANSPARENT is enabled, false for disable it. Default is disabled.
  - setTcpDeferAccept
```
public IOUringServerSocketChannelConfig setTcpDeferAccept(int deferAccept)
```
    Set the TCP_DEFER_ACCEPT option on the socket. See man 7 tcp for more details.
  - getTcpDeferAccept
```
public int getTcpDeferAccept()
```
    Returns a positive value if TCP_DEFER_ACCEPT is enabled.
  - getTcpFastopen
```
public int getTcpFastopen()
```
    Returns threshold value of number of pending for fast open connect.
    
    See Also:
    
    RFC 7413 Passive Open
  - setTcpFastopen
```
public IOUringServerSocketChannelConfig setTcpFastopen(int pendingFastOpenRequestsThreshold)
```
    Enables tcpFastOpen on the server channel. If the underlying os doesn't support TCP_FASTOPEN setting this has no effect. This has to be set before doing listen on the socket otherwise this takes no effect.
    
    Parameters:
    
    pendingFastOpenRequestsThreshold - number of requests to be pending for fastopen at a given point in time for security.
