18a8365992 cfg80211: introduce scan IE limit attribute
This patch introduces a new attribute for a wiphy that tells
userspace how long the information elements added to a probe
request frame can be at most. It also updates the at76 to
advertise that it cannot support that, and, for now until I
can fix that, iwlwifi too.

c02cf3738c ath9k: pass regd structure directly to regulatory functions
All regulatory information is encapsulated by the ath9k_regulatory
struct, so we can now change all the callers to take that directly
instead of struct ath_hw.  This in turn will enable us to move the
regulatory functions to common code also used by ath5k, since both
can use this regulatory struct.

55a3757a57 iwlwifi: change check triggering device restart after rfkill change
The STATUS_ALIVE value cannot be used because it is cleared when
interface is brought down and will not be set if rfkill is enabled when
interface is started again. The interface can thus not be brought up if
rfkill was enabled before stopping the interface and disabled after
starting the interface.

Change the test to use priv->is_open instead, this will be set when
interface is started whether rfkill is enabled or not.

Thanks to Helmut Schaa for the suggested fix.

dce072580e p54: more SoftLED updates
This patch hopefully finishes the SoftLED code:
- It adds two more LEDs (rx and radio).
  (the FW claims it can support up to 16 LEDs,
   but I doubt that any vendor put more than 4 on a board)
- update the LEDs in a _delayed_ workqueue.
  No one reported any more crashes.
  (see: "PATCH] p54: fix race condition in memory management")
  So we can stop burning the mm code.

42639fcd44 ath5k: reduce exported channel list
Claiming every available 5 ghz channel has a couple of negative
side-effects: scanning takes a long time, and the channel list
overflows the available buffer space for netlink commands,
resulting in:

    $ iw phy phy0 info
    command failed: No buffer space available (-105)

This patch adds a modparam so people who want to see all the channels
can do so by passing all_channels=1.  By default users will see a
smaller list of channels.  This also halves scan time, from 10 seconds
down to less than 5 when using world regulatory.
