7934e24983 net: lwm2m: retry registration update 6 seconds before expiration
When the priority of the LwM2M engine was lowered, it causes an
occasional registration update to fall outside of the registration
lifetime.  This shows up as the following error:
Failed with code 4.4. Retrying registration

Let's try and retry a bit earlier to account for the priority
change.

c0e0d6131d net: rpl: Fix malformed Kconfig default
'default false' should have been 'default n', though they happen to have
the same effect here, due to undefined Kconfig symbols ('false')
evaluating to 'n' in a boolean sense.

Kconfig bool symbols implicitly default to 'n', so remove the default
rather than fixing it.

ce6f9819e0 net: Remove redundant NETWORKING dependency
The 'source' of subsys/net/ip/Kconfig in subsys/net/Kconfig is already
within an 'if NETWORKING' block, so the NETWORKING dependency in
subsys/net/ip/Kconfig is redundant.

Remove the redundant dependency.

This gets rid of a bunch of 'NETWORKING && NETWORKING' dependencies in

The IP stack drops any TCP segment which doesn't fit into our

segments, which are segments, usually with data length of 1, which

eb3ecf6e66 net: shell: conn: Always show TCP state
It's rather confusing to not see current TCP state in any way (it
makes distinguishing different TCP contexts very hard). And nobody
can know/remember that it's printed with CONFIG_NET_DEBUG_TCP
defined. So, just make it be printed always (initially I thought
about printing just numeric value if CONFIG_NET_DEBUG_TCP isn't
defined, but why, if we can print symbolic name easily).

Also, add a hint that defining CONFIG_NET_DEBUG_TCP will still
print even more info (like unacked pkt list) - similarly to
similar helpful hints we have in other parts of net shell.

dcb0ac1256 net: tc: dont yield during net_rc tx/rx workq init
We init the net_tc tx/rx work queues during net_init() with a
call to init_rx_queues().  The L2/L3 and networking drivers have been
setup at this point.  If we yield the current thread, we risk
a call to net_recv_data() which calls net_queue_rx() which calls
net_tc_submit_to_rx_queue() on an RX work queue which hasn't been
setup yet.

4c58ffb5ab net: lwm2m: dont release reply for duplicate block transfer
During normal use, a CoAP packet can be resent due to network congestion
and other causes.  During block transfer the LwM2M client checks to make
sure the block received is the one we expect and if not generates a
"duplicate" warning.  When this happened, we were releasing the reply
handler and when the correct block was received the client would
generate a "No handler" error.

To avoid releasing the reply handler too early, let's set the coap_reply
"user_data" field to an error condition (1).  Then, once the reply
processing is complete we can check the user_data field to be sure that
it's ok to release the reply handler.
