It appears that MPTCP in the kernel doesn't support the TCP_DEFER_ACCEPT socket option.

When starting apache 2 httpd with LD_PRELOAD=/usr/lib64/mptcpize/libmptcpwrap.so (which is provided by https://github.com/intel/mptcpd), this error is logged at startup:

[core:warn] [pid 2238878:tid 139880911450688] (95)Operation not supported: AH00076: Failed to enable APR_TCP_DEFER_ACCEPT

For http, the warning can be ignored as far as I can tell.

However, there are other applications that will fail if this socket option isn't supported, such as those based on Apache Thrift. For example, MapD fails with:

TServerSocket::listen() setsockopt() TCP_DEFER_ACCEPT Protocol not available
