Expected behavior

The values sendBufferSize and receiveBufferSize from the SocketTransportDescriptor adequately reflect the buffer sizes of the created UDP sockets.

Current behavior

The values sendBufferSize and receiveBufferSize from the SocketTransportDescriptor and SocketTransportDescriptor::min_send_buffer_size() method return larger values than the actual size of the UDP socket buffers.

Steps to reproduce

Using the fields sendBufferSize and receiveBufferSize from the SocketTransportDescriptor , you must set a value greater than net.core.wmem_max or net.core.rmem_max.
