* SMB: tree_connect
*
* When a client connects to a server resource, an SMB_COM_TREE_CONNECT
* message is generated to the server. This command is almost exactly like
* SMB_COM_TREE_CONNECT_ANDX, except that no AndX command may follow; see
* section 4.1.4.
*
* Client Request Description
* ================================== =================================
*
* UCHAR WordCount; Count of parameter words = 0
* USHORT ByteCount; Count of data bytes; min = 4
* UCHAR BufferFormat1; 0x04
* STRING Path[]; Server name and share name
* UCHAR BufferFormat2; 0x04
* STRING Password[]; Password
* UCHAR BufferFormat3; 0x04
* STRING Service[]; Service name

* The CIFS server responds with:

* Server Response Description
* ================================ =================================
*
* UCHAR WordCount; Count of parameter words = 2
* USHORT MaxBufferSize; Max size message the server handles
* USHORT Tid; Tree ID
* USHORT ByteCount; Count of data bytes = 0
*
* If the negotiated dialect is MICROSOFT NETWORKS 1.03 or earlier,
* MaxBufferSize in the response message indicates the maximum size message
* that the server can handle. The client should not generate messages,
* nor expect to receive responses, larger than this. This must be
* constant for a given server. For newer dialects, this field is ignored.
*
* Tid should be included in any future SMBs referencing this tree
* connection.
