must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured

well since mac80211 needs to lose the logic to
start the mesh on interface up.

We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.

In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.

ath9k_hw: fix endian issues with CTLs on AR9003

Parsing data using bitfields is messy, because it makes endian handling
much harder. AR9002 and earlier got it right, AR9003 got it wrong.
This might lead to either using too high or too low tx power values,
depending on frequency and eeprom settings.
Fix it by getting rid of the CTL related bitfields entirely and use
masks instead.

ath9k: Fix bug in reading input gpio state for ar9003

The register which gives input gpio state is 0x404c for ar9003,
currently 0x4048 is wrongly used. This will disable RF and make
it unusable on some of AR9003.

Change the module parameter name to bt_ch_inhibition from
bt_ch_announce to better describe the functionality

In order to allow Bluetooth to activate a smart AFH mechanism

BT Core to inhibit its activity in channels that interfere

Set module parameter "bt_ch_inhibition=0" will disable the channel

PCI L1 Active needs to be disabled while loading the uCode so that the bus
doesn't go to sleep. The enablement of L1 Active should be done after
the uCode has sent the ALIVE response. The enablement of L1 Active was
missing.
Enabling L1 Active allows to save power if the BIOS / bus driver allows
it.

I measured the power consumption while not associated and
idle/associated:
L1 Active disabled: 39 mA = 130mW
L1 Active enabled:   6 mA = 20 mW
