/***
* A class derived from TFTPRequestPacket definiing a TFTP read request packet type.
*
* Details regarding the TFTP protocol and the format of TFTP packets can be found in RFC 783. But
* the point of these classes is to keep you from having to worry about the internals. Additionally,
* only very few people should have to care about any of the TFTPPacket classes or derived classes.
* Almost all users should only be concerned with the {@link panda.net.tftp.TFTPClient} class
* {@link panda.net.tftp.TFTPClient#receiveFile receiveFile()} and
* {@link panda.net.tftp.TFTPClient#sendFile sendFile()} methods.
