When we receive CoAP packets, it is in input buffer
that is size of NET_IPV6_MTU.
So in reality, we can handle bigger Block-Wise writes
than CONFIG_LWM2M_COAP_BLOCK_SIZE.
So if parsing of CoAP packet has passed, continue
with the same block-size instead of going to default.

Until recently, the posix api was purely a consumer of the
network subsystem. However, a dependency cycle was added as
a stop-gap solution for challenges with the native platform.
Specifically,
1. eventfd symbols conflict with those of the host
2. eventfd was excluded from native libc builds via cmake
If any part of the posix were then to select the network
subsystem (which is a legitimate use case, given that networking
is a part of the posix api), we would get a build error due to
the Kconfig dependency cycle.
As usual, with dependency cycles, the cycle can be broken
via a third, mutual dependency.
What is the third mutual dependency? Naturally, it is ZVFS
which was planned some time ago. ZVFS will be where we
collect file-descriptor and FILE-pointer APIs so that we can
ensure consistency for Zephyr users.
This change deprecates EVENTFD_MAX in favour of
ZVFS_EVENTFD_MAX.

The POSIX_MAX_FDS option does not correspond to any standard
POSIX option. It was used to define the size of the file
descriptor table, which is by no means exclusively used by
POSIX (also net, fs, ...).
POSIX_MAX_FDS is being deprecated in order to ensure that
Zephyr's POSIX Kconfig variables correspond to those defined in
the specification, as of IEEE 1003.1-2017. Namely,
POSIX_OPEN_MAX. CONFIG_POSIX_MAX_OPEN_FILES is being deprecated
for the same reason.
To mitigate any possible layering violations, that option is
not user selectable. It tracks the newly added
CONFIG_ZVFS_OPEN_MAX option, which is native to Zephyr.
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_DEVICE_IO
Similarly, with this deprecation, we introduce the following
Kconfig options that map directly to standard POSIX Options by

* CONFIG_POSIX_DEVICE_IO_ALIAS_CLOSE
* CONFIG_POSIX_DEVICE_IO_ALIAS_OPEN
* CONFIG_POSIX_DEVICE_IO_ALIAS_READ
* CONFIG_POSIX_DEVICE_IO_ALIAS_WRITE
Gate open(), close(), read(), and write() via the
CONFIG_POSIX_DEVICE_IO Kconfig option and move

An earlier pull request implementing observe support was merged too
hastily. It had a few issues:
1. The predicate for whether a request should be marked not ongoing was
wrong (it checked ret != 0 instead of ret < 0)
2. Without observes in mind, MID-based deduplication is not a required
feature. Deduplication was handled implicitly - the exchange would get
dropped after the first response anyway, so duplicate responses would
not get matched to anything. But with observes, there are several
responses in an exchange. This commit adds this.
3. Using coap_request_is_observe(&internal_req->request) in the response
handler requires the whole request to stay in scope for the lifetime of
the observation, which I observed was not always the case. Adding an
is_observe bool to the internal struct improved stability significantly.
With these fixes, GETs with observe option works very well.

The CONFIG_NET_SOCKETS_POSIX_NAMES option is marked as deprecated in
favor of using normal POSIX socket API includes found under the
include/zephyr/posix directory. If you want to use BSD socket API calls,
you need to select POSIX_API and use the socket headers found in the
POSIX subsystem. If you do not want to or cannot enable POSIX_API,
then you must use zsock_ prefix when working with BSD socket calls.

As stated in "[RFC7959], Section 2.5":
"The Block1 Option provides no way for a single endpoint to perform
multiple concurrently proceeding block-wise request payload transfer
(e.g., PUT or POST) operations to the same resource. Starting a new
block-wise sequence of requests to the same resource (before an old
sequence from the same endpoint was finished) simply overwrites the
context the server may still be keeping."

Zephyr's DHCPv4 server does not implement persistent storage of address
leases. In result, all leases are lost on reboot, which can cause
delays with clients starting in INIT-REBOOT state and thus sending
(potentially several) Requests before attempting full Discover-Request
procedure.
Add option to override RFC defined behavior, which states that if we
don't recognize the client sending the Request, the server shall remain
silent. Enabling that option allows the server to send NAK reply in case
client is not recognized, informing the client it should proceed with
full procedure.

With recently introduced DNS retransmission mechanism, a certain bug
could occur when calculating query timeout.
If the time until the final DNS timeout (as indicated by
CONFIG_NET_SOCKETS_DNS_TIMEOUT) was less than 1 millisecond, the actual
millisecond timeout value was rounded down, resulting in 0 ms timeout.
This in order was interpreted as invalid argument by dns_get_addr_info()
function, so in result, instead of reporting query timeout, the function
reported invalid argument error.
Fix this by rounding the millisecond timeout up, instead of down, so
that in any case, if the final timeout is not due, we always provide
non-zero timeout to dns_get_addr_info().

In iperf2, for multicast data, if it is a client, it will not wait for
the server's AckFIN packet. Because the iperf2 server will not send an

waits for the server's AckFIN packet.

The netmask should be tied to the IPv4 address instead of being
global for the network interface.
If there is only one IPv4 address specified to the network interface,
nothing changes from user point of view. But if there are more than
one IPv4 address / network interface, the netmask must be specified
to each address separately.
This means that net_if_ipv4_get_netmask() and net_if_ipv4_set_netmask()
functions should not be used as they only work reliably if there is
only one IPv4 address in the network interface.
The new net_if_ipv4_get_netmask_by_addr() and
net_if_ipv4_set_netmask_by_addr() functions should be used as they make
sure that the netmask is tied to correct IPv4 address in the network
interface.
