The ap_ht tests used to execute iw reg set command using the subprocess
python module. Start using the cmd_execute() general function for
executing shell commands so that this would also work on remote setups.

The test cases ap_ht40_5ghz_invalid_pair and ap_ht40_5ghz_disabled_sec
mixed use of apdev[0] and apdev[1] while only needing a single AP. This
works when both the devices are on the same host (e.g., with
mac80211_hwsim), but not when using separate remote hosts. Fix this by
using apdev[0] more consistently in these test cases.

Pass apdev param to hostapd.add_bss(). Kill hardcoded phy param and get
phy base on apdev. These are needed to support operation with a remote
test host.

Pass the full apdev to the add_ap() function instead of just ifname.
This allows us to handle also remote hosts while we can check
apdev['hostname'], apdev['port'].
This step (1) converts the cases where apdev[#]['ifname'] was used as
the argument to hostapd.add_ap().

This test case for enforcing that AP setup fails in case there is need
to fall back to 20 MHz channel due to invalid 40 MHz configuration.
Modify this to allow successful AP startup as long as 40 MHz channel
does not get enabled.

It was possible for a cached scan entry in cfg80211 from an earlier test
case to show up while verifying that the disabled AP does not show up in
scan results. This could result in invalid test failures, e.g., when
running test cases "ap_require_ht ap_multi_bss_config" multiple times
(depends a bit on timing). Make this less likely to occur by explicitly
clearing the scan cache and by stopping wlan1 from trying to associate
before stopping ap_required_ht* test cases.

On recent kernels, it seems that something changed (scheduler?)
that makes hwsim send the scan done event so quickly that iw isn't
scheduled back in to listen for it, causing iw to get stuck.
Work around this by using the scan trigger command (it'll be quick
enough so that we don't really need to wait) and the scan trigger
and dump commands where the results are required (and use a small
sleep there instead of waiting for the scan results.)
I'll try to fix this separately in iw later.

ap_ht_smps needs relatively recern kernel support, so allow it to be

The previous design did not actually break from the wait loop when the
AP changed back to 40 MHz channel and as such, ended up waiting the full
30 second time. Furthermore, the five second delay time for returning
back to 40 MHz was not sufficiently long to test behavior correctly
since the STA did not have any chances of returning the next coex report
before the AP had returned to 40 MHz. Increase the AP wait time to 15
seconds so that the once per 10 seconds OBSS scan from the STA gets in
before changing back to 40 MHz channel (after the 40 MHz intolerant AP
gets disabled).

It was possible for regulatory domain changes to "leak" into following
test cases in number of cases where the cfg80211 BSS table remained
after regulatory domain had been restored to world roaming. Try to make
this less likely to occur by explicitly clearing BSS table at the end of
test cases that use different regulatory domain. This makes P2P test
cases that verify channel selection based on world roaming rules more
robust.

The issue in mac80211 was identified and proposed fix is now available,
so remove the workaround here and start reporting failures from
unexpected disconnection during CSA.

It looks like cfg80211 can trigger disconnection even without disabling
HT, so the same issue may be hit with both of the channel switches in
these test cases.

ap_ht40_csa and ap_ht40_csa3 seem to show a cfg80211/mac80211 issue
where a CSA from HT40+ to HT40- channel results in HT getting disabled
due to cfg80211_chandef_compatible() check on c1->width == c2->width
claiming that the new channel is not compatible. For now, comment out
the FAIL case for these known issues to avoid constant failure for cases
that are not wpa_supplicant/hostapd issues. Once the kernel side design
has been reviewed, these error cases can be enabled here.

It takes some time for hostapd to complete AP startup. In some cases,
this could potentially result in station starting a scan before the AP
is beaconing or ready to reply to probes. To avoid such race conditions,
wait for AP-ENABLED before going ahead with the test cases.
