__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.

API except for the monitor channel and in libertas,
clarify this. Split the libertas mesh use into a

set_channel() to set_monitor_channel().
Also describe the desired set_monitor_channel()

Allow the driver to wake/stop the queues for multiple reasons. A queue
is started when no stop-reasons exist.
Convert all wake/stop queue calls to use the new API.
Before, a stopped queue was almost synonymous a high-watermark on Tx.
Remove a bit of code in wl12xx_tx_reset() that relied on it.
Internal packets arriving from mac80211 are also discarded when a queue
is stopped. A notable exception to this is the watermark reason, which
is a "soft"-stop reason. We allow traffic to gradually come to a halt,
but we don't mind spurious packets here and there. This is merely a flow
regulation mechanism.

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.
