Rather than raise error on connect if iface is down, just take the iface
up.
Rather than raise error on disconnect if iface is down, just ignore the
disconnection request.
Adjust tests and documentation accordingly.
This should make the API easier to use for applications and is more in
line with the original L2 agnostic connectivity RFC.
Also replace some instances of net_if_flag_is_set with
net_if_is_admin_up, which is cleaner and identical in function.

The current method for handling DAD directly tracks a DAD state for each
iface.
This does not reflect the fact that each individual IP has a separate
DAD state.
This also does not align with the logic in conn_mgr_initial_state, which
instead uses net_if_ipv6_get_global_addr(NET_ADDR_PREFERRED, ...).
Thus, the current approach falsely reports IPv6 ready when DAD adds
the link_addr, and also fails to report IPv6 ready if DAD is disabled.
This commit removes DAD tracking completely, and relies solely on
net_if_ipv6_get_global_addr(NET_ADDR_PREFERRED, ...), fixing both
problems, and simplifying the event tracking.
For consistency, slight modifications to IPv4 handling as well.

Currently, conn_mgr fires L4_CONNECTED and L4_DISCONNECTED events for
every individual iface that gains or loses connectivity.
After this commit, these events are only fired when the first iface gains
connectivity, and the last iface loses connectivity, respectively.
This is so that applications can rely on conn_mgr as a simple way to
track whether connectivity is available.

Adds a flag to allow ifaces and L2s to be ignored.
This is so that applictions have better control over what ifaces they
want connectivity management for.
Enabling the flag forces conn_mgr to consider the iface
unready.
Also increase NET_CONNECTION_MANAGER_PRIORITY default value from 0 to 1
so that applications can register SYS_INIT callbacks that fire just
before conn_mgr initializes. This allows ignored ifaces to be configured
before conn_mgr starts, if needed.

In preparation for altering the conditions under which conn_mgr
fires NET_EVENT_L4_CONNECTED and NET_EVENT_L4_DISCONNECTED,

These changes do not alter the behavior of conn_mgr. They merely change
how that behavior is expressed so that it is easier to understand, and so
that upcoming changes are easier to implement.

Add CDC Ethernet Control Model class implementation for the
new experimental USB device support based on the existing
implementation subsys/usb/device/class/netusb/function_ecm.c.
The implementation forms virtual ethernet connection between
USB host and USB device and requires two corresponding MAC
addresses, one for the virtual interface on the device side,
and other for the host which is described by a string descriptor.
With upcoming changes it should also possible to use a real
ethernet controller as media access on the device side.
CDC ECM implementation supports multiple instances which are
specified using DT. The number of instances is limited by the
number of endpoints on the controller, two to three should usually
be possible.

As `net_if_get_link_addr()` returns a pointer to the link layer

Instead of having a single global mutex, covering, in most cases
unrelated, access to all network interfaces, introduce a separate mutex
for each network interface.
Wherever interface function operates on an individual interface context
data, use local mutex protection instead. The global mutex remains only
to protect access to shared resources (IPv4/6 context pool, timer lists
etc.).
Finally, rework the timer expiry handlers, to prevent interface
functions from being called while the global lock is held (the global
mutex has to be held when iterating over the timer list, as lists are
not thread safe). The reason for this is to avoid possible deadlock
scenario. The global mutex is sometimes being locked, while inside
interface function (protected by a local mutex), so if it was allowed
the other way as well, a deadlock could occur.

Whenever a CSIS instance is registered with
bt_csip_set_member_register we now properly check if the
set size, rank and lock characteristics should be present.
If not, then remove them from the service declaration.
It is done this way, as it is easier (read: possible) to
remove characteristics from the service declarations,
than it is to add the optional characteristics, as the
optional characteristics may be present in some CSIS
instances, but not in others.

LLDP start timer is executed when iface is up
at startup, then once more when iface up event
is received.
When iface is up before net_lldp_init call, then multiple
entries are added to the lldp_ifaces related to the
same iface.
That leads to continuous loop execution within
lldp_tx_timeout.

doesn't append new entry into the slist.

Reworks the zephyr macros and pools to be objects in their own right. Each
pool can be statically defined with a Z_ private macro. The objects can
then be initialized with an rtio instance statically.
This cleans up a lot of code that was otherwise doing little bits of
management around allocation/freeing and reduces the scope those functions
has to the data it needs.
This should enable sharing the pools of sqe, cqe, and mem blocks among rtio
instances in a future improvement easily.

Rather than the rings, which weren't shared between userspace and kernel
space in Zephyr like they are in Linux with io_uring, use atomic mpsc
queues for submission and completion queues.
Most importantly this removes a potential head of line blocker in the
submission queue as the sqe would be held until a task is completed.
As additional bonuses this avoids some additional locks and restrictions
about what can be submitted and where. It also removes the need for
two executors as all chains/transactions are done concurrently.
Lastly this opens up the possibility for a common pool of sqe's to
allocate from potentially saving lots of memory.
