Silently drop the IPv6 Neighbor Advertisement if we receive it
for an unknown neighbor or if there some some issue in the packet.
Returning error here would cause the ICMP module to print an
actual error which just pollutes the log without any apparent
benefit.

If server registration fails, allow fallback to secondary server,
or fallback to bootstrap.
Also allow fallback to different bootstrap server.
Add API to tell RD client when server have been disabled by
executable command.
Changes to RD state machine:
* All retry logic should be handled in NETWORK_ERROR state.
* New state SERVER_DISABLED.
* Internally disable servers that reject registration
* Temporary disable server on network error.
* Clean up all "disable timers" on start.
* Select server first, then find security object for it.
* State functions return void, error handling is done using states.
* DISCONNECT event will only come when client is requested to stop.
* NETWORK_ERROR will stop engine. This is generic error for all kinds
of registration or network failures.
* BOOTSTRAP_REG_FAILURE also stops engine. This is fatal, and we cannot
recover.
Refactoring:
* Server selection logic is inside server object.
* sm_handle_timeout_state() does not require msg parameter. Unused.
* When bootstrap fail, we should NOT back off to registration.
This is a fatal error, and it stops the engine and informs application.

React to disable executable, as well as add callback that allows
disabling server for a period of time.
Also add API that would find a next server candidate based on the
priority and server being not-disabled.
Move all server related functions into its own header.

The net_if_ipv6_set_hop_limit() API was missing the "_if_"

Commit 55802e5e86 fixed error handling of
TX errors, in case ARP request was generated. There are however also

This commit fixes those cases in ethernet_send(), where function would

When interface names are enabled, a default name is applied

Fix the possible race between TCP work items already scheduled for
execution, and tcp_conn_unref(), by moving the actual TCP context
releasing to the workqueue itself. That way we can be certain, that when
the work items are cancelled, they won't execute. It could be the case,
that the work item was already being processed by the work queue, so
clearing the context could lead to a crash.
Remove the comments around the mutex lock in the work handlers regarding
the race, as it's not the case anymore. I've kept the locks however, as
they do make sense in those places.

values. Use those generic setters when storing the desired

values. Use those generic getters when fetching the desired

Noticed mixed usage (bool vs int) for txtime option. Changed
the code to use int type like in other options.
The uint16_t option getter gets the value from uint16_t variable
but returns int value to the caller, and also expects that user
supplies int value.
For uint8_t value, it is expected that uint8_t value is supplied
instead of int.

The Zephyr's core ethernet code had to be adjusted to support setting T1S
PLCA parameters from user Zephyr programs.
Such approach allows more flexibility, as T1S network configuration;
especially PLCA node numbers, can be assigned not only via device tree
at compile time. For example user can read them from EEPROM and then
configure the network accordingly.
For now - the union in struct ethernet_t1s_param only consists of plca
structure. This can change in the future, when other T1S OA parameters -
like Receive/Transmit Cut-Through Enable (bits RXCTE/TXCTE in OA_CONFIG0
register) are made adjustable from user program.
