ieee80211_offchannel_enable_all_ps function is no longer used

Ideally, hardware/firmware initialization is complete after the
drv_start routine. In mac80211 restart code (ieee80211_reconfig),
defer calling the driver commands i.e. setup fragmentation
threshold, rts threshold and coverage class till drv_start
routine is called.

kernel panic occurs when we create an IBSS mode and leave it for
sometime without any joiner and this is introduced by the
commit ec2b774e7c91094d8c00de579646f1162b87b01e where we don't
put proper braces for 'list_for_each_entry_safe' and we pass an
invalid 'sta' pointer to __sta_info_destroy
EIP is at __list_add+0xe/0xa0

when we run high bandwidth UDP traffic and we trigger a scan, the scan
state machine seems to be looping in SUSPEND->RESUME->DECISION->SUSPEND
and SET_CHANNEL seems to be never called as 'tx_empty' is never true
while running UDP traffic. fix this by settting SET_CHANNEL state when
we get into RESUME state.

Error handling code following a kmalloc should free the allocated data.
The label fail_alloc already does this for rfkill.
A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)

return@p2 ...;
)

p2 << r.p2;

If the vif is stopped while it is offchannel (e.g. right
after p2p negotiation) the SDATA_STATE_OFFCHANNEL flag
is never get cleared, resulting in various bad effects
(e.g. GO can't start beaconing).
Fix it by clearing the SDATA_STATE_OFFCHANNEL flag
even if the vif is stopped.

Wireless will select a different hardware queue based on the
top 3 bits of the diffserv field, for ipv4. Extend that queue
selection mechanism to ipv6, and make the calls orthogonal.

Following the tradition we have had with ath5k, ath9k, CRDA,
wireless-regdb I'd like to license this code under the permissive ISC
license for the code sharing purposes with other OSes, it'd sure be nice
to help the landscape in this area. Although I am %82.89 owner of the
regulatory code I have asked every contributor to the regulatory code
and have receieved positive Acked-bys from everyone except two deceased
entities:
o Frans Pop RIP 2010 [0]
- Frans Pop <elendil@planet.nl>
- Frans Pop <fjp@debian.org>
o Nokia RIP February, 11, 2011 [1], [2]
- ext-yuri.ershov@nokia.com
- kalle.valo@nokia.com
Frans Pop's contribution was a simple patch 55f98938, titled,
"wireless: remove trailing space in messages" which just add a \n
to some printk lines. I'm going to treat these additions as
uncopyrightable.
As for the contributions made by employees on behalf of Nokia
my contact point was Petri Karhula <petri.karhula@nokia.com> but
after one month he noted he had not been able to get traction from the
legal department on this request, as such it I proceeded by replacing
their contributions in previous patches.
The end goal is to help a clean rewrite that starts in userspace
that is shared under ISC license which currently is taking place with
the regulatory simulator [3].

Nokia hasn't gotten back to me in over 1 month for a relicense
change request. There are only a few changes that they contributed,
so just reverting their changes but replacing with another set.
This change replaces this commit:
commit 269ac5fd2d75b118d76a2291e28796527db2f3f8

cfg80211: indent regulatory messages with spaces
The regulatory messages in syslog look weird:
kernel: cfg80211: Regulatory domain: US
kernel: ^I(start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
kernel: ^I(2402000 KHz - 2472000 KHz @ 40000 KHz), (600 mBi, 2700 mBm)
kernel: ^I(5170000 KHz - 5190000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5190000 KHz - 5210000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5210000 KHz - 5230000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5230000 KHz - 5330000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 3000 mBm)
Indent them with four spaces instead of the tab character to get prettier
output.

Nokia hasn't gotten back to me in over 1 month for a relicense
change request. There are only a few changes that they contributed,
so just reverting their changes but replacing with another set.
This change replaces this commit:
commit c4c322941ce0d7e2b7b8794ad70683123d9cb26a

cfg80211: Update of regulatory request initiator handling
In some cases there could be possible dereferencing freed pointer. The
update is intended to avoid this issue.

This seems to not serve any purpose anymore, at least all frame
processing afterwards seems to be able to deal with QoS frames. So,
let's save the expensive memmove and just leave the QoS header in the
802.11 frame for further processing.

This ensures a linear behaviour when filling /proc/net/if_inet6 thus making
ifconfig run really fast on IPv6 only addresses. In fact, with this patch and
the IPv4 one sent a while ago, ifconfig will run in linear time regardless of
address type.
IPv4 related patch: f04565ddf52e401880f8ba51de0dff8ba51c99fd
dev: use name hash for dev_seq_ops

Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop
route for the interface we're adding an addres to was wrong (see commit
7ffbcecbeed91e5874e9a1cfc4c0cbb07dac3069). for one, it never triggers, and two,
it was completely wrong to begin with. This test was meant to cover this
section of RFC 4429:
3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration
* (modifies section 5.5) A host MAY choose to configure a new address
as an Optimistic Address. A host that does not know the SLLAO
of its router SHOULD NOT configure a new address as Optimistic.
A router SHOULD NOT configure an Optimistic Address.
This patch should bring us into proper compliance with the above clause. Since
we only add a SLAAC address after we've received a RA which may or may not
contain a source link layer address option, we can pass a pointer to that option
to addrconf_prefix_rcv (which may be null if the option is not present), and
only set the optimistic flag if the option was found in the RA.
Change notes:
(v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than
a pointer to make its use more clear as per request from davem.

SFQ q->perturbation is used in sfq_hash() as an input to Jenkins hash.
We currently randomize this 32bit value only if a perturbation timer is
setup.
Its much better to always initialize it to defeat attackers, or else
they can predict very well what kind of packets they have to forge to
hit a particular flow.

Since commit 817fb15dfd98 (net_sched: sfq: allow divisor to be a
parameter), we can leave perturbation timer armed if a memory allocation
error aborts sfq_init().
Memory containing active struct timer_list is freed and kernel can
crash.
Call sfq_destroy() from sfq_init() to properly dismantle qdisc.

Define special location values for RX NFC that request the driver to
select the actual rule location. This allows for implementation on
devices that use hash-based filter lookup, whereas currently the API is
more suited to devices with TCAM lookup or linear search.
In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy
the structure back to user-space after insertion so that the actual
location is returned.

When cancelling a delayed work (timer) in L2CAP we can not sleep holding
the sock mutex otherwise we might deadlock with an L2CAP timer handler.
This is possible because RX/TX and L2CAP timers run in different workqueues.
The scenario below illustrates the problem. Thus we are now avoiding to
sleep on the timers locks.

The hci_task_lock mutex (previously a lock) was supposed to protect the
register/unregister of HCI protocols against RX/TX tasks. This will not
be needed anymore because SCO and L2CAP will always be compiled.
Moreover, with the recent move of RX/TX to workqueues per device the
global hci_task_lock was causing starvation between different HCI
devices.

When mac80211 relays a frame from STA1 to STA2 in AP mode it will get
re-classified in the tx path. Unfortunately the frame protocol field
is always set to ETH_P_8023 while the classification only kicks in
for ETH_P_IP. Hence, a high priority frame from STA1 will be send to
STA2 as best effort.
Instead of running classification on the frame just use the same
priority as STA1 did. Do this by adding 256 to the skb->priority
to allow cfg80211_classify8021d to shortcut frame classification.

Making use of rcu_dereference_protected to fix the problem.
V2:
- Replacing rcu_dereference with rcu_dereference_protected
as suggested by Johannes.
- Adding mutex_lock/unlock to satisfy the condition at
