d3606cd255 doc: move EnableIPv6 under Network
The EnableIPv6 option is incorrectly documented under General but should
be documented under Network instead.

62d31539d6 configure.ac: fix static build with readline
Retrieve the dependencies of readline through pkg-config (and fallback
to -lreadline) to avoid the following build failure:

f5a30a1cfc station: Don't expire BSSes between freq subset scans
Add a parameter to station_set_scan_results to allow skipping the
removal of old BSSes.  In the DBus-triggered scan only expire BSSes
after having gone through the full supported frequency set.

It should be safe to pass partial scan results to
station_set_scan_results() when not expiring BSSes so using this new
parameter I guess we could also call it for roam scan results.

e3bece76f9 station: Split DBus scans into 3 frequency subsets
A scan normally takes about 2 seconds on my dual-band wifi adapter when
connected.  The drivers will normally probe on each supported channel in
some unspecified order and will have new partial results after each step
but the kernel sends NL80211_CMD_NEW_SCAN_RESULTS only when the full
scan request finishes, and for segmented scans we will wait for all
segments to finish before calling back from scan_active() or
scan_passive().

To improve user experience define our own channel order favouring the
2.4 channels 1, 6 and 11 and probe those as an individual scan request
so we can update most our DBus org.connman.iwd.Network objects more
quickly, before continuing with 5GHz band channels, updating DBus
objects again and finally the other 2.4GHz band channels.

The overall DBus-triggered scan on my wifi adapter takes about the same
time but my measurements were not very strict, and were not very
consistent with and without this change.  With the change most Network
objects are updated after about 200ms though, meaning that I get most
of the network updates in the nm-applet UI 200ms from opening the
network list.  The 5GHz band channels take another 1 to 1.5s to scan and
remaining 2.4GHz band channels another ~300ms.

Hopefully this is similar when using other drivers although I can easily
imagine a driver that parallelizes 2.4GHz and 5GHz channel probing using
two radios, or uses 2, 4 or another number of dual-band radios to probe
2, 4, ... channels simultanously.  We'd then lose some of the
performance benefit.  The faster scan results may be worth the longer
overall scan time anyway.
I'm also assuming that the wiphy's supported frequency list is exactly
what was scanned when we passed no frequency list to
NL80211_CMD_TRIGGER_SCAN and we won't get errors for passing some
frequency that shouldn't have been scanned.

01c108938e test-runner: Use DBus for hwsim radios
Use the hwsim DBus API rather than command line. This both is
faster and more dynamic than doing so with the command line.
This also avoids tracking the radio ID since we can just hang
on to the radio Dbus object directly.

6a1853b01a hwsim: change radio Create() to take a dictionary
The Create() API was limited to only taking a Name and boolean
(for p2p enabling). The actual hwsim nl80211 API can take more
attributes than this (which are actually utilized when creating
from the command line). To get the DBus API up to the same
functionality the two arguments in Create were replaced with
a single dictionary. This allows for extending later if more
arguments are needed.

799ab03f59 hwsim: check pending_create_msg before replying
In the NEW_RADIO callback hwsim was assuming that DBus had no
yet replied to the Create() method. In some cases the NEW_RADIO
event fires before the actual callback which will respond to
DBus. This causes a crash in the create callback.

fde1012f5d auto-t: add static netconfig test
Tests netconfig with a static configuration, as well as tests ACD
functionality.

The test has two IWD radios which will eventually use the same IP.
One is configured statically, one will receive the IP via DHCP.
The static client sets its IP first and begins using it. Then the
DHCP client is started. Since ACD in a DHCP client is configured
to use its address indefinitely, the static client *should* give
up its address.

f39d1b4ac2 netconfig: add ACD client for static configuration
When the IP is configured to be static we can now use ACD in
order to check that the IP is available and not already in
use. If a conflict is found netconfig will be reset and no IP
will be set on the interface. The ACD client is left with
the default 'defend once' policy, and probes are not turned
off. This will increase connection time, but for static IP's
it is the best approach.

d2cc033d09 auto-t: pass namespace on to other IWD classes
Certain classes were still using the default namespace. This
didn't matter yet since testAP was the only test using namespaces,
and the AP interface was the only one being used.

For an IWD station on a separate namespace all objects need to
be accessable, so the namespace is passed along to those as needed.

b647f8e1f0 network: clear info of removed known network before disconnect
Make sure to erase the network_info of a known network that has been
removed before disconnecting any stations connected to it. This fixes
the following warning observed when forgetting a connected network:

  WARNING: ../git/src/network.c:network_rank_update() condition n < 0 failed

This also fixes a bug where such a forgotten network would incorrectly
appear as the first element in the response to GetOrderedNetworks().  By
clearing the network_info, network_rank_update() properly negates the
rank of the now-unknown network.

This patch converts the code to use the new l_rtnl_address class.  The

Also, address removal path for static addresses has been removed, since

e1e1c4edd1 test-runner: introduce network namespaces
Our simulated environment was really only meant to test air-to-air
communication by using mac80211_hwsim. Protocols like DHCP use IP
communication which starts to fall apart when using hwsim radios.
Mainly unicast sockets do not work since there is no underlying
network infrastructure.

In order to simulate a more realistic environment network namespaces
are introduced in this patch. This allows wireless phy's to be added
to a network namespace and unique IWD instances manage those phys.
This is done automatically when 'NameSpaces' entries are configured
in hw.conf:

[SETUP]
num_radios=2

[NameSpaces]
ns0=rad1,...

This will create a namespace named ns0, and add rad1 to that
namespace. rad1 will not appear as a phy in what's being called the
'root' namespace (the default namespace).

As far as a test is concerned you can create a new IWD() class and
pass the namespace in. This will start a new IWD instance in that
namespace:

ns0 = ctx.get_namespace('ns0')
wd_ns0 = IWD(start_iwd=True, namespace=ns0)

'wd_ns0' can now be used to interact with IWD in that namespace, just
like any other IWD class object.

845658bd32 station: get neighbor reports early
Waiting to request neighbor reports until we are in need of a roam
delays the roam time, and probably isn't as reliable since we are
most likely in a low RSSI state. Instead the neighbor report can
be requested immediately after connecting, saved, and used if/when
a roam is needed. The existing behavior is maintained if the early
neighbor report fails where a neighbor report is requested at the
time of the roam.

The code which parses the reports was factored out and shared
between the existing (late) neighbor report callback and the early
neighbor report callback.
