Members
       index       The number of this Security Profile Descriptor in the
                   Security Profile Descriptor List.

       flags       Security Profile Descriptor Flags bitmask, see enum
                   nbft_security_flags.

       secret_type Secret Type, see enum nbft_security_secret_type.

       sec_chan_algs
                   Secure Channel Algorithm list: an array of bytes whose
                   values are the Security Type (SECTYPE) field, see enum
                   nvmf_tcp_sectype. NULL if not present in the NBFT heap.

       sec_chan_algs_len
                   Length in bytes of sec_chan_algs.

       auth_protocols
                   Authentication Protocol identifier list. Values are
                   Authentication Protocol Identifiers as defined in the NVM
                   Express Base Specification. NULL if not present in the NBFT
                   heap.

       auth_protocols_len
                   Length in bytes of auth_protocols.

       cipher_suites
                   Cipher Suite identifier list: raw byte data containing
                   cipher suite identifiers as defined in the IANA TLS
                   Parameters Registry. Each entry is a 16-bit value; the
                   number of entries is cipher_suites_len / 2.  NULL if not
                   present in the NBFT heap.

       cipher_suites_len
                   Length in bytes of cipher_suites.

       kx_groups   KX-HMAC-CHAP key exchange group identifier list.  Values
                   are Key Exchange Group Identifiers as defined in the NVM
                   Express Base Specification. NULL if not present in the NBFT
                   heap.

       kx_groups_len
                   Length in bytes of kx_groups.

       sec_hash_funcs
                   KX-HMAC-CHAP hash function identifier list, see enum
                   libnvmf_hmac_alg. NULL if not present in the NBFT heap.

       sec_hash_funcs_len
                   Length in bytes of sec_hash_funcs.

       secret_keypath
                   URI string for the secret key path. The type of the URI is
                   specified by secret_type.  NULL if not present.

Description
       All pointer fields refer to storage owned by the parent struct
       libnbft_info. They must not be freed separately.
