- *
- * In the netconn implementation, there are three ways to block a client:
- *
- * - accept mbox (sys_arch_mbox_fetch(&conn->acceptmbox, &accept_ptr, 0); in netconn_accept())
- * - receive mbox (sys_arch_mbox_fetch(&conn->recvmbox, &buf, 0); in netconn_recv_data())
- * - send queue is full (sys_arch_sem_wait(LWIP_API_MSG_SEM(msg), 0); in lwip_netconn_do_write())
- *
- * The events have to be seen as events signaling the state of these mboxes/semaphores. For non-blocking
- * connections, you need to know in advance whether a call to a netconn function call would block or not,
- * and these events tell you about that.
- *
- * RCVPLUS events say: Safe to perform a potentially blocking call call once more.
- * They are counted in sockets - three RCVPLUS events for accept mbox means you are safe
- * to call netconn_accept 3 times without being blocked.
- * Same thing for receive mbox.
- *
- * RCVMINUS events say: Your call to to a possibly blocking function is "acknowledged".
- * Socket implementation decrements the counter.
- *
- * For TX, there is no need to count, its merely a flag. SENDPLUS means you may send something.
- * SENDPLUS occurs when enough data was delivered to peer so netconn_send() can be called again.
- * A SENDMINUS event occurs when the next call to a netconn_send() would be blocking.

- *
- * The function should return a pointer to a character string which is the

- * browser, for example "/thanks.htm" or "/response/error.ssi".
- *
- * The maximum number of parameters that will be passed to this function via

- * the incoming HTTP request above this number will be discarded.
- *
- * Requests intended for use by this CGI mechanism must be sent using the GET

- * array (currently .shtml, .shtm, .ssi, .xml, .json) where "name" appears as

- * within JavaScript and, hence, leaving the tag in place will result in
- * problems in these cases. In order to avoid these problems, define
- * LWIP_HTTPD_SSI_INCLUDE_TAG as zero in your lwip options file, or use JavaScript

-/**
- * @file
- *
- * IPv6 address scopes, zones, and scoping policy.
- *
- * This header provides the means to implement support for IPv6 address scopes,
- * as per RFC 4007. An address scope can be either global or more constrained.
- * In lwIP, we say that an address "has a scope" or "is scoped" when its scope
- * is constrained, in which case the address is meaningful only in a specific
- * "zone." For unicast addresses, only link-local addresses have a scope; in
- * that case, the scope is the link. For multicast addresses, there are various
- * scopes defined by RFC 4007 and others. For any constrained scope, a system
- * must establish a (potentially one-to-many) mapping between zones and local
- * interfaces. For example, a link-local address is valid on only one link (its
- * zone). That link may be attached to one or more local interfaces. The
- * decisions on which scopes are constrained and the mapping between zones and
- * interfaces is together what we refer to as the "scoping policy" - more on
- * this in a bit.
- *
- * In lwIP, each IPv6 address has an associated zone index. This zone index may
- * be set to "no zone" (IP6_NO_ZONE, 0) or an actual zone. We say that an
- * address "has a zone" or "is zoned" when its zone index is *not* set to "no
- * zone." In lwIP, in principle, each address should be "properly zoned," which
- * means that if the address has a zone if and only if has a scope. As such, it
- * is a rule that an unscoped (e.g., global) address must never have a zone.
- * Even though one could argue that there is always one zone even for global
- * scopes, this rule exists for implementation simplicity. Violation of the
- * rule will trigger assertions or otherwise result in undesired behavior.
- *
- * Backward compatibility prevents us from requiring that applications always
- * provide properly zoned addresses. We do enforce the rule that the in the
- * lwIP link layer (everything below netif->output_ip6() and in particular ND6)
- * *all* addresses are properly zoned. Thus, on the output paths down the
- * stack, various places deal with the case of addresses that lack a zone.
- * Some of them are best-effort for efficiency (e.g. the PCB bind and connect
- * API calls' attempts to add missing zones); ultimately the IPv6 output
- * handler (@ref ip6_output_if_src) will set a zone if necessary.
- *
- * Aside from dealing with scoped addresses lacking a zone, a proper IPv6
- * implementation must also ensure that a packet with a scoped source and/or
- * destination address does not leave its zone. This is currently implemented
- * in the input and forward functions. However, for output, these checks are
- * deliberately omitted in order to keep the implementation lightweight. The
- * routing algorithm in @ref ip6_route will take decisions such that it will
- * not cause zone violations unless the application sets bad addresses, though.
- *
- * In terms of scoping policy, lwIP implements the default policy from RFC 4007
- * using macros in this file. This policy considers link-local unicast
- * addresses and (only) interface-local and link-local multicast addresses as
- * having a scope. For all these addresses, the zone is equal to the interface.
- * As shown below in this file, it is possible to implement a custom policy.
