ef3a62d272 mac80211: detect driver tx bugs
When a driver rejects a frame in it's ->tx() callback, it must also
stop queues, otherwise mac80211 can go into a loop here. Detect this
situation and abort the loop after five retries, warning about the
driver bug.

3a5be7d4b0 Revert "mac80211: Use skb_header_cloned() on TX path."
This reverts commit 608961a5ec.

The problem is that the mac80211 stack not only needs to be able to
muck with the link-level headers, it also might need to mangle all of
the packet data if doing sw wireless encryption.

This fixes kernel bugzilla .  Thanks to Didier Raboud (for the
bugzilla report), Andrew Prince (for bisecting), Johannes Berg (for
bringing this bisection analysis to my attention), and Ilpo (for
trying to analyze this purely from the TCP side).

In 2.6.27 we can take another stab at this, by using something like
skb_cow_data() when the TX path of mac80211 ends up with a non-NULL
tx->key.  The ESP protocol code in the IPSEC stack can be used as a
model for implementation.

872ba53395 mac80211: decrease IBSS creation latency
Sufficient scans (at least 2 or 3) should have been done within 7
seconds to find an existing IBSS to join.  This should improve IBSS
creation latency; and since IBSS merging is still in effect, shouldn't
have detrimental effects on eventual IBSS convergence.

c97c23e386 mac80211: fix alignment issue with compare_ether_addr()
This addresses an alignment issue with compare_ether_addr().
The addresses passed to compare_ether_addr should be two bytes aligned.
It may function properly in x86 platform. However may not work properly
on IA-64 or ARM processor.

This also fixes a typo in mlme.c where the sk_buff struct name is incorect.
Though sizeof() works for any incorrect structure pointer name as its just
a pointer length that we want, lets just fix it.

70d251b24c mac80211: Fix for NULL pointer dereference in sta_info_get()
This addresses a NULL pointer dereference in sta_info_get().
TID and sta_info are extracted in ADDBA Timer expiry function
through the timer handler's argument.

The problem is extracging the TID (which was stored in
timer_to_tid[] array of type "u8") through "int *" typecast which
may also yield unwanted bytes for the MSB of TID that results
in incorrect sta_info and ieee80211_local pointers.

ieee80211_local pointer is NULL as illustrated below, it crashes in
sta_info_get(). The problem started when extracting ieee80211_local
pointer out of sta_info iteself and eventually crashed in
stat_info_get().

The proper way to fix is to change the data type of TID to u8
instead of u16. However changing all the occurences requires
some prototype changes as well. We should fix this in upcoming
patches.

2f561feb38 mac80211: Add RTNL version of ieee80211_iterate_active_interfaces
Since commit e38bad4766
	mac80211: make ieee80211_iterate_active_interfaces not need rtnl
rt2500usb and rt73usb broke down due to attempting register access
in atomic context (which is not possible for USB hardware).

This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock,
and provides the non-RTNL version under a new name:
	ieee80211_iterate_active_interfaces_atomic()

So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those
drivers require the RTNL version of ieee80211_iterate_active_interfaces().
Since they already call that function directly, this patch will automatically
fix the USB rt2x00 drivers.

339a7c41c9 mac80211: Do not free net device after it is unregistered.
The error path in ieee80211_register_hw() may call the unregister_netdev()
and right after it - the free_netdev(), which is wrong, since the
unregister releases the device itself.

So the proposed fix is to NULL the local->mdev after unregister is done
and check this before calling free_netdev().

I checked - no code uses the local->mdev after unregister in this error
path (but even if some did this would be a BUG).

Certain APs like D-link does not set the fifth bit in WMM IE.

If it is set then only ieee80211_ht_cap is sent during association request.
So n-only association fails.
And this patch fixes this problem by copying the wmm_info to wmm_ie,

30b89b0f5e mac80211: rework scanning to account for probe response/beacon difference
This patch reworks the scanning code (ieee80211_rx_bss_info) to take
more parameters from beacons and keep a BSS info structure alive when
only beacons for it are received. This fixes a problem with iwlwifi
drivers (where we don't understand the root cause of the problem yet)
and another driver for some broken hardware (which cannot send probe
requests unless associated, so can't always actively scan.)

245cbe7a65 mac80211: fix key todo list order
When we add multiple todo entries, we rely on them being executed
mostly in the right order, especially when a key is being replaced.
But when a default key is replaced, the todo list order will differ
from the order when the key being replaced is not a default key, so
problems will happen. Hence, just move each todo item to the end of
the list when it is added so we can in the other code ensure that
hw accel for a key will be disabled before it is enabled for the
replacement.
