The read implementation.
The value of m_len returned controls further processing. The callback function is only invoked when m_len is positive; any data read is not processed when m_len is negative; reading stops when m_len is zero.
The management of memory associated with m_buf must be compatible with the read callback.
Implements ns3::FdReader.
