bd80affa3f Bluetooth: Support connection parameter update as central
bt_conn_le_param_update returns -EBUSY when used in central
role if peer did not support LE connection parameter
request.

This commit allows a central role to use either LE
connection parameter request, if local controller supports
it, else use LE connection update.

Added checks for latency and timeout changes requested in
bt_conn_le_param_update, to decide if connection parameter

24c7397160 Bluetooth: Controller: Increase default TX buffer count
Only 1 TX buffer is sub-optimal for performance since the controller
would always have to wait for the host TX thread to give it another
buffer. Increase the value to 2 so the controller can keep
transmitting data without waiting for the host.

f5383b07a2 Bluetooth: AT: Fix reset the state during error
1. Reset the state when error occurs
2. This patch avoids checking for the AT_STATE_UNSOLICITED_CMD state
as the loop exits with possix error. So check for at->state
AT_STATE_START is sufficient for loop termination.
3. Fix different sign warning.

Print TCP header information in one line as there is really no
need to use multiple lines. Also use debug level when printing
the header info so that it is only seen if debugging is activated.

081246737c net/http: let HTTP_SERVER, HTTP_CLIENT and HTTP_PARSER select HTTP
Due to commit 8308b9bd2d ("net/http: Add the HTTP/1.1 API")
every user of CONFIG_HTTP_PARSER would need to add CONFIG_HTTP to
their .conf files.  Which is fine for intree samples/tests as they
have been adjusted, but the rest of world working on Zephyr apps
will need to make this changes as well.

Instead, we should have each of the following select HTTP instead of
depend on it, which will make future use of these configs and their
dependencies more intuitive:
HTTP_SERVER
HTTP_CLIENT
HTTP_PARSER

NOTE: As cleanup, this commit also removes the CONFIG_HTTP added to
samples and test .conf files.

in RX path if we receive lot of packet from the network and never get

d48ef44d25 net: 6lo: Fix typo in compress bit calculation
commit 2e3e93dccb ("net: 6lo: Fix compress bit calculation") adds
a bit shift to the compress bit calculation, however it's typo'd as
a greater than comparison causing get_6co_compress() to return a
boolean value rather than the shifted version of the calculation.

82545373ee net/mgmt: Remove the list node before unlocking the semaphore
The caller semaphore was released too early, this can cause the caller
to re-use the data and possibly corrupt the memory, if caller yields
and is run before this management thread. Solution is to first remove
the node from the list and then unlock the semaphore.

157c383260 net: ipv6: Make config options more fine grained
Add CONFIG_NET_IPV6_NBR_CACHE option that is the base for both
neighbor discovery (ND) and duplicate address detection (DAD).

Both ND and DAD can be disabled if needed. If NBR cache is
disabled, then ND and DAD are disabled too.

Note that it makes not much sense to disable DAD or NBR cache
as IPv6 will not work properly without them. It is possible
to disable ND but then the neighbor information needs to come
via other sources like RPL.
