Because per-interface statistics rely on interface pointer stored in a
net_pkt, it should not be unreferenced before stats are updated.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
Functions for per-interface statistics collection used a pointer to a
packet that could've been deallocated in the net_conn callback function.
In result, application could crash when interface related to the packet
was referenced. To fix that, packet interface is stored earlier, so it
can be used instead for statistics collection.

The IP stack drops any TCP segment which doesn't fit into our
receive window. However, we still must accept Zero Window Probe
segments, which are segments, usually with data length of 1, which
a peer sends to us after we stayed with zero window for some time.
In this case, we need to repeat an ACK with the old ack number.

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.

With updates to bt_gatt_notify and bt_gatt_indicate it is now possible
to pass the Characteristic attribute instead of its value which makes
the code able to verify if attribute properties are set correctly.
Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
Since BT_GATT_CHARACTERISTIC now expands to 2 attributes it may be
confusing to use bt_gatt_indicate as that expects the Value attribute to
be given which is no longer visible, so this enables the user to use
the Characteristic attribute in addition to its value.

Only the first one requires it. Actually drivers know that already and

In case ethernet has to run along with 15.4 on the same SoC, this will
optimize things quite a bit knowing that biggest ethernet frame will be

The adv_send() function was incorrectly decoding the 5-bit value (it
was using it directly as milliseconds), which effectively lead to the
code always picking the controller's minimum supported interval.
Fix this issue, but do it by simplifying the (re)transmission state
tracking so that the state is always stored in the original "packed"
8-bit value, where 5 bits are reserved for the interval, and 3 for the
count.

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.
