/* D.2 TpmTcpProtocol.h */
/* D.2.1. Introduction */
/* TPM commands are communicated as BYTE streams on a TCP connection.  The TPM command protocol is
   enveloped with the interface protocol described in this file. The command is indicated by a
   UINT32 with one of the values below.  Most commands take no parameters return no TPM errors.  In
   these cases the TPM interface protocol acknowledges that command processing is complete by
   returning a UINT32=0. The command TPM_SIGNAL_HASH_DATA takes a UINT32-prepended variable length
   BYTE array and the interface protocol acknowledges command completion with a UINT32=0. Most TPM
   commands are enveloped using the TPM_SEND_COMMAND interface command. The parameters are as
   indicated below.  The interface layer also appends a UIN32=0 to the TPM response for
   regularity. */
