The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).

Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.

Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.

Using skb_header_cloned to check if it's safe to write to the skb is not
enough - mac80211 also touches the tailroom of the skb.
Initially this check was only used to increase a counter, however this

head/tailroom was needed:

This should decrease un-necessary flushes, on/off channel work,
and channel changes in cases where the only scanned channel is
the current operating channel.

* Removes SCAN_OFF_CHANNEL flag, uses SDATA_STATE_OFFCHANNEL
  and is-scanning flags instead.

* Add helper method to determine if we are currently configured
  for the operating channel.

* Do no blindly go off/on channel in work.c  Instead, only call
  appropriate on/off code when we really need to change channels.
  Always enable offchannel-ps mode when starting work,
  and disable it when we are done.

* Consolidate ieee80211_offchannel_stop_station and
  ieee80211_offchannel_stop_beaconing, call it
  ieee80211_offchannel_stop_vifs instead.

* Accept non-beacon frames when scanning on operating channel.

* Scan state machine optimized to minimize on/off channel
  transitions.  Also, when going on-channel, go ahead and
  re-enable beaconing.  We're going to be there for 200ms,
  so seems like some useful beaconing could happen.
  Always enable offchannel-ps mode when starting software
  scan, and disable it when we are done.

* Grab local->mtx earlier in __ieee80211_scan_completed_finish

On review of 'zd1211rw: implement beacon fetching and handling
ieee80211_get_buffered_bc()', Christian Lamparter noted that [1]:

   Since zd_beacon_done also uploads the next beacon so long in advance,
   there could be an equally long race between the outdated state of the
   next beacon's DTIM broadcast traffic indicator (802.11-2007 7.3.2.6)
   which -in your case- was uploaded almost a beacon interval ago and
   the xmit of ieee80211_get_buffered_bc *now*.

   The dtim bc/mc bit might be not set, when a mc/bc arrived after the
   beacon was uploaded, but before the "beacon done event" from the
   hardware. So, dozing stations don't expect the broadcast traffic
   and of course, they might miss it completely.

   It's probably better to fix this in mac80211 (see the attached hack).

Some drivers (e.g. ath9k) do not always disable beacons when they're
supposed to. When an interface is changed using the change_interface op,
the mode specific sdata part is in an undefined state and trying to
get a beacon at this point can produce weird crashes.

To fix this, add a check for ieee80211_sdata_running before using

The Mesh Control header only includes 0, 1 or 2 addresses. If there is
one address, it should be interpreted as Address 4.  If there are 2,
they are interpreted as Addresses 5 and 6 (Address 4 being the 4th
address in the 802.11 header).

The address extension used to hold up to 3 addresses instead of the current 2.
I'm not sure which draft version changed this, but it is very unlikely that it
will change again given the state of the approval process of this draft.  See
section 7.1.3.6.3 in current draft (8.0).

Also, note that the extra address that I'm removing was not being used, so this
change has no effect on over-the-air frame formats.  But I thought I better
remove it before someone does start using it.

Fix this by making a local copy of shared skbs prior to mangeling them.
To avoid copying the skb unnecessarily move the skb_copy call below the
checks that don't need write access to the skb.

Also, move the assignment of nh_pos and h_pos below the skb_copy to point
to the correct skb.

It would be possible to avoid another resize of the copied skb by using
skb_copy_expand instead of skb_copy but that would make the patch more
complex. Also, shared skbs are a corner case right now, so the resize
shouldn't matter much.

This is confusing when the data rate is actually much higher.

Hence, only update the last_tx_rate field with tx rate information

In order for frame injection to work properly for some use cases
(e.g., finding the station entry and keys for encryption), mac80211
needs to find the correct sdata entry. This works when the main vif
is in AP mode, but commit a2c1e3da
broke this particular use case for station main vif. While this type of
injection is quite unusual operation, it has some uses and we should fix
it. Do this by changing the monitor vif sdata selection to allow station
vif to be selected instead of limiting it to just AP vifs. We still need
to skip some iftypes to avoid selecting unsuitable vif for injection.

Allow drivers to specify their own set of cipher
suites to advertise vendor-specific ciphers. The
driver is then required to implement hardware
crypto offload for it.

Currently, mac80211 translates the cfg80211
cipher suite selectors into ALG_* values.
That isn't all too useful, and some drivers
benefit from the distinction between WEP40
and WEP104 as well. Therefore, convert it
all to use the cipher suite selectors.

In the function ieee80211_subif_start_xmit the logic related with
meshdrlen is under CONFIG_MAC80211_MESH macro, but in one place it isn't.
This is some update for this

I just had the following:

iwlagn 0000:02:00.0: Attempting to modify non-existing station 107

Note that 107 == 0x6b which is slab poison.

The reason is that mac80211 passed a freed station
pointer to mac80211, because as it happened iwlwifi
reset itself while mac80211 was disconnecting from
the network.

It turns out that we do take care to look up the
station pointer in ieee80211_tx_pending_skb, but
then don't use it, which obviously is a bug. Fix
this by removing the ieee80211_tx_h_sta handler
and assigning the station pointer directly.
