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.
