wl1271: Fix to join and channel number handling

This patch changes the way JOIN's are performed, and channel numbers updated.
The reason for this is that the firmware JOIN command clears WPA(2) key
material, and if done while associated to a WPA(2) secured AP, will render
the data-path unusable.

While the channel is not usually changed while associated (and currently we
could not even support something like that), after performing a scan operation
while associated, mac80211 will re-set the current channel to the driver. This
caused our problem.

Also, the mac80211 is assuming that the driver channel configuration remains
persistent over periods of IDLE. Therefore remove channel resetting to zero
from the unjoin function.

through the normal SKB queue maintained in hif_usb,

mac80211: improve HT channel handling

Currently, when one interface switches HT mode,
all others will follow along. This is clearly
undesirable, since the new one might switch to
no-HT while another one is operating in HT.

Address this issue by keeping track of the HT
mode per interface, and allowing only changes
that are compatible, i.e. switching into HT40+
is not possible when another interface is in
HT40-, in that case the second one needs to
fall back to HT20.

Also, to allow drivers to know what's going on,
store the per-interface HT mode (channel type)
in the virtual interface's bss_conf.

Johannes Berg [Wed, 5 May 2010 13:25:02 +0000]
cfg80211/mac80211: better channel handling

Currently (all tested with hwsim) you can do stupid
things like setting up an AP on a certain channel,
then adding another virtual interface and making
that associate on another channel -- this will make
the beaconing to move channel but obviously without
the necessary IEs data update.

In order to improve this situation, first make the
configuration APIs (cfg80211 and nl80211) aware of
multi-channel operation -- we'll eventually need
that in the future anyway. There's one userland API
change and one API addition. The API change is that
now SET_WIPHY must be called with virtual interface
index rather than only wiphy index in order to take
effect for that interface -- luckily all current
users (hostapd) do that. For monitor interfaces, the
old setting is preserved, but monitors are always
slaved to other devices anyway so no guarantees.

The second userland API change is the introduction
of a per virtual interface SET_CHANNEL command, that
hostapd should use going forward to make it easier
to understand what's going on (it can automatically
detect a kernel with this command).

Other than mac80211, no existing cfg80211 drivers
are affected by this change because they only allow
a single virtual interface.

mac80211, however, now needs to be aware that the
channel settings are per interface now, and needs
to disallow (for now) real multi-channel operation,
which is another important part of this patch.

One of the immediate benefits is that you can now
start hostapd to operate on a hardware that already
has a connection on another virtual interface, as
long as you specify the same channel.

Note that two things are left unhandled (this is an
improvement -- not a complete fix):

 * different HT/no-HT modes

   currently you could start an HT AP and then
   connect to a non-HT network on the same channel
   which would configure the hardware for no HT;
   that can be fixed fairly easily

 * CSA

   An AP we're connected to on a virtual interface
   might indicate switching channels, and in that
   case we would follow it, regardless of how many
   other interfaces are operating; this requires
   more effort to fix but is pretty rare after all

ar9170usb: remove deprecated aggregation code

This patch removes the incomplete AMPDU implementation in ar9170usb.

The code in question is:
 * too big and complex (more than 550 SLOC.)
   This is enough to qualify for a new separate code file!

 * unbalanced quantity & quality
over-engineered areas like:
* xmit scheduling and queuing frames for multiple HT peers
* redundant frame sorting
are confronted by gaping holes:
* accurate transmission feedback
* firmware error-handling and device reset
* HT rate control algorithm

 * error-prone
Since its inclusion, hardly anything was done to fix
any of the outlined flaws from the initial commit message.

   => This also indicates poor maintainability.

 * relies heavily on several spinlocks.

As a result of this shortcomings, the code is slow and does not
even support the most basic 11n requirement: HT station mode.

Therefore, I request to purge my heap of **** from the kernel:
"ar9170: implement transmit aggregation".

The next item on the agenda is: (re-)start from scratch with
an adequate design to accommodate the special requirements
and features of the available frameworks and tools.

sense if the BSSID isn't also fixed, but it need

for all the "agn" NICs, there is no statistics information available
for mac80211 get_stats() call. Remove the callback function to

iwlwifi: work around passive scan issue

Some firmware versions don't behave properly when
passive scanning is requested on radar channels
without enabling active scanning on receiving a
good frame. Work around that issue by asking the
firmware to only enable the active scanning after
receiving a huge number of good frames, a number
that can never be reached during our dwell time.

iwl: cleanup: remove unneeded error handling

This is just a cleanup and doesn't change how the code works.

debugfs_create_dir() and debugfs_create_file() return an error pointer
(-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs
they return NULL.  This is how they are implemented and what it says in
the DebugFS documentation.  DebugFS can not be compiled as a module.

As a result, we only need to check for error pointers and particularly
-ENODEV one time to know that DebugFS is enabled.  This patch keeps the
first check for error pointers and removes the rest.

The other reason for this patch, is that it silences some Smatch warnings.
Smatch sees the condition "(result != -ENODEV)" and assumes that it's
possible for "result" to equal -ENODEV.  If it were possible it would lead
to an error pointer dereference.  But since it's not, we can just remove
the check.

mac80211: fix rts threshold check

Currently whenever rts thresold is set, every packet will use RTS
protection no matter its size exceeds the threshold or not. This is
due to a bug in the rts threshold check.
if (len > tx->local->hw.wiphy->rts_threshold) {
txrc.rts = rts = true;
}
Basically it is comparing an int (len) and a u32 (rts_threshold),
and the variable len is assigned as:
len = min_t(int, tx->skb->len + FCS_LEN,
 tx->local->hw.wiphy->frag_threshold);
However, when frag_threshold is "-1", len is always "-1", which is
0xffffffff therefore rts is always set to true.
