[linux-cifs-client] Help with error codes and configuration

[Christopher R. Hertel]

It would help if the command numbers were presented in hex rather than
decimal, since all of the documentation provides hex.

See:
http://www.ubiqx.org/cifs/rfc-draft/draft-leach-cifs-v1-spec-02.html#s6.1

That's a pretty good list of the actual command codes.  In the list below:
  4 = 0x04 = SMB_COM_CLOSE
 47 = 0x2F = SMB_COM_WRITE_ANDX
 50 = 0x32 = SMB_COM_TRANSACTION2
162 = 0xA2 = SMB_COM_NT_CREATE_ANDX

I've seen something like this before, a long time ago.  In that case, an
earlier command was causing an error which was closing the connection.

The mid value is just a number assigned to a thread to ensure that the
response is delivered to the correct thread.

I'm not sure what -5 and -11 mean here.
