Re: [Patch 01/10] MdePkg: Add TLS related protocol definition

["Long, Qin" <qin.long@intel.com>]

Reviewed-by: Qin Long <qin.long@intel.com>

Please correct some typos later:
EFI_TLS_EXTENDION  --> EFI_TLS_EXTENSION
TLS/SSLhandshake --> TLS/SSL handshake
cerfificate --> certificate
cypher --> cipher
binaryX.509 --> binary X.509
PEMencoded --> PEM-encoded

Best Regards & Thanks,
LONG, Qin
