| Provide BSD Sockets like API on top of native Zephyr networking API. |

| config NET_SOCKETS_POSIX_NAMES |
| bool "Standard POSIX names for Sockets API" |
| help |
| By default, Sockets API function are prefixed with ``zsock_`` to avoid |
| namespacing issues. If this option is enabled, they will be provided |
| with standard POSIX names like socket(), recv(), and close(), to help |
| with porting existing code. Note that close() may require a special |
| attention, as in POSIX it closes any file descriptor, while with this |
| option enabled, it will still apply only to sockets. |

| config NET_SOCKETS_POLL_MAX |
| int "Max number of supported poll() entries" |

| Maximum number of entries supported for poll() call. |

| Enable TLS socket option support which automatically establishes |
| a TLS connection to the remote host. |

| config NET_SOCKETS_ENABLE_DTLS |
| bool "Enable DTLS socket support [EXPERIMENTAL]" |

| Enable DTLS socket support. By default only TLS over TCP is supported. |

| config NET_SOCKETS_DTLS_TIMEOUT |
| int "Timeout value in milliseconds for DTLS connection" |

| depends on NET_SOCKETS_ENABLE_DTLS |
| help |
| This variable specifies time in milliseconds after which DTLS |
| connection is considered dead by TLS server and DTLS resources are |
| freed. This is needed to prevent situation when DTLS client shuts down |
| without closing connection gracefully, which can prevent other peers |
| from connecting. Value of 0 indicates no timeout - resources will be |
| freed only when connection is gracefully closed by peer sending TLS |
| notification or socket is closed. |

| This variable sets maximum number of TLS/DTLS ciphersuites that can |
| be used with specific socket, if set explicitly by socket option. |
| By default, all ciphersuites that are available in the system are |
| available to the socket. |
