FixpositionDriver::Read(), the TCP branch callsread(sensor_fd_, buf, sizeof(buf)).Since
bufis auint8_t*parameter,sizeof(buf)evaluates to the pointer size (8 bytes on 64-bit), not the buffer capacity carried by thesizeargument. As a result, every TCP read is capped at 8 bytes regardless of the buffer passed in.
