/* D.3 TpmTcpProtocol.h */
/* D.3.1. Introduction */
/* TPM commands are communicated as uint8_t 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_t with one of the values below. Most commands take no parameters and return no TPM errors. In
these cases the TPM interface protocol acknowledges that command processing is completed by
returning a uint32_t = 0. The command TPM_SIGNAL_HASH_DATA takes a uint32_t-prepended variable length
byte array and the interface protocol acknowledges command completion with a uint32_t = 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_t = 0 to the TPM response for
regularity. */
