> Unlike the linux, windows and macOS, AIX uses the default implementation for socket options such as ipDontFragmentSupported(), keepAliveOptionsSupported(), setTcpkeepAliveProbes, getTcpkeepAliveProbes, setQuickAck, getQuickAck and more, where it either returns false or exception. These options can be implemented on AIX with the supported flags like SO_PEERID, TCP_NODELAYACK is the equivalent AIX option for TCP_QUICKACK and IPPROTO_TCP, IP_DONTFRAG.
