When performing a HW restart for an AP mode interface, add stations back
only after the AP is beaconing. This mimics the normal flow of STA
addition on AP.

Some devices (wlcore) do not support adding stations before beaconing,
so this has the added benefit of making recovery work for them.

The remain-on-channel time validation shouldn't
depend on the value of HZ, as it does now with
the check against jiffies, since then you might
use a value that works on one system but not on
another. Fix it by checking against a minimum
that's fixed.

Also add validation of the wait duration for a
management frame TX since this also translates
into remain-on-channel internally.

drv_resume can get called without a prior call to drv_suspend.
Consider the following steps:

1. Suspend is started but driver's drv_suspend returns error.
2. Suspend is aborted. local->wowlan flag is left set.
3. Interface is removed.
4. Suspend again. This time open_count is 0 so drv_suspend is
   not called and local->wowlan not cleared.
5. On resume ieee80211_reconfig will call drv_resume since

__rfkill_switch_all() switches the state of devices of a given type; however,
it does not switch devices of all type (RFKILL_TYPE_ALL). As a result, it
ignores the keycode "KEY_RFKILL" from another module, i.e. eeepc-wmi.

This fix is to make __rfkill_switch_all() to be able to switch not only
devices of a given type but also all devices.

clarify this. Split the libertas mesh use into a

set_channel() to set_monitor_channel().

Also describe the desired set_monitor_channel()

Just like the AP mode patch, instead of setting
the channel and then joining the mesh network,
provide the channel to join the network on to
the join_mesh() function.

Like in AP mode, you can also give the channel
to the join-mesh nl80211 command now.

Unlike AP mode, it picks a default channel if
none was given.

As libertas uses mesh mode interfaces but has
no join_mesh callback and we can't simply break
it, keep some compatibility code for that case
and configure the channel directly for it.

In the non-libertas case, where we store the
channel until join, allow setting it while the
interface is down.

If it worked (Felix says it doesn't right now), the
typical use-case for WDS interfaces would be to be
slaved to AP mode interfaces. Therefore, it isn't
necessary to set the channel on WDS interfaces. As
they don't support powersave or anything like that,
they also couldn't use a different channel anyway.

Instead of setting the channel first and then
starting the AP, let cfg80211 store the channel
and provide it as one of the AP settings.

This means that now you have to set the channel
before you can start an AP interface, but since
hostapd/wpa_supplicant always do that we're OK
with this change.

Alternatively, it's now possible to give the
channel as an attribute to the start-ap nl80211
command, overriding any preset channel.

There's no need for ieee80211_set_channel to check
