Macros
#define	NRF_SOCKET_TLS_MAX_MESSAGE_SIZE   2048
	Maximum TLS message size in bytes.
#define	NRF_SOCKET_TLS_MAX_SEC_TAG_LIST_SIZE   7
	Maximum number of security tags that can be associated with a socket.
#define	NRF_SO_SEC_TAG_LIST   1
	Write-only socket option to select the security tags to be used. This option accepts a list of.
#define	NRF_SO_SEC_HOSTNAME   2
	Socket option to set the hostname used for peer verification. This option accepts a string containing the hostname, and its length. The length may be set to zero to disable hostname verification.

	Socket option to retrieve the cipher suite used during the TLS/DTLS handshake.
#define	NRF_SO_SEC_PEER_VERIFY   5
	Socket option to set peer verification level. See TLS peer verification options for a list of allowed values.
#define	NRF_SO_SEC_ROLE   6
	Write-only socket option to set role for the connection. See Role for the socket connection for a list of allowed values.
#define	NRF_SO_SEC_SESSION_CACHE   12
	Socket option to control TLS session caching. See TLS session cache options for a list of allowed values.
#define	NRF_SO_SEC_SESSION_CACHE_PURGE   13
	Socket option to purge session cache immediately. This option accepts any value.
#define	NRF_SO_SEC_DTLS_HANDSHAKE_TIMEO   14
	Socket option to set DTLS handshake timeout value. See DTLS handshake timeout values for allowed values.
#define	NRF_SO_SEC_DTLS_CID   15
	Socket option to enable/disable the connection ID. See DTLS Connection ID settings for allowed values.
#define	NRF_SO_SEC_DTLS_CID_STATUS   16
	Socket option to get the connection ID status. See DTLS Connection ID statuses for allowed values.
#define	NRF_SO_SEC_DTLS_CONN_SAVE   17
	Socket option to save DTLS connection.
#define	NRF_SO_SEC_DTLS_CONN_LOAD   18
	Socket option to load DTLS connection.
#define	NRF_SO_SEC_HANDSHAKE_STATUS   19
	Socket option to get end status of last completed TLS/DTLS handshake procedure. See TLS/DTLS Handshake statuses for allowed values.
