2c7e6bc9ac mac80211: disallow fixing bitrates with hw rate control
When hw rate control is used, these parameters have
no meaning because the hardware cannot get at them
right now, so disallow setting them. Also clean up
the function a bit.

5d1ec85f00 mac80211: dont try to use existing sta for AP
Clean out some cruft that could use an already existing
sta_info struct -- that case cannot happen. Also, there's
a bug there -- if allocation/insertion fails then it is
possible that we are left in a lingering state where
mac80211 waits for the AP, cfg80211 waits for mac80211,
but the AP has already replied. Since there's no way to
indicate an internal error, pretend there was a timeout,
i.e. that the AP never responded.

5fba4af32c cfg80211: avoid sending spurious deauth to userspace
Before
  commit ca9034592823e8179511e48a78731f95bfdd766c
  Author: Holger Schurig <hs4233@mail.mn-solutions.de>
  Date:   Tue Oct 13 13:45:28 2009 +0200

      cfg80211: remove warning in deauth case

we assumed that drivers never give us spurious deauth
frames because they filter them out based on the auth
state they keep track of. This turned out to be racy,
because userspace might deauth while the AP is also
sending a deauth frame, so the warning was removed.

However, in that case we should not tell userspace
about the AP's frame if it requested deauth "first",
where "first" means it came to cfg80211 first.

According to Ralink source code, the RX frame format is RXINFO + RXWI +

Doing this, we fix the L2PAD bit which is now correctly set on received

2e331462fc rt2x00: Reorganize L2 padding inserting function.
Simplify the rt2x00queue_insert_l2pad function by handling the alignment
operations one by one. Do not special case special circumstances.
Basically first perform header alignment, and then perform payload alignment
(if any payload does exist). This results in a properly aligned skb.

The end result is better readable code, with better results, as now L2 padding
is inserted only when a payload is actually present in the frame.

a9e1cb6a78 iwlwifi: add continuous uCode event log capability
In order to help uCode debugging, adding the capability to provide
continuous uCode event logging function.

uCode events is located in round-robin event queue and filled by uCode,
by enable continuous event logging, driver check the write pointer
and log the newly added events in iwl_bg_ucode_trace() timer function.

There is still possibility of missing events if event queue being
wrapped before next event dump; but with this capability, we can have
much better understanding of the uCode behavior during runtime; it can
help to debug the uCode related issues.

Methods to enable/disable the continuous event log:
step 1: enable ucode trace timer
     "echo 1 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"
step 2: start ftrace
     sudo ./trace-cmd record -e iwlwifi_ucode:* sleep 1d
step 3: stop ftrace
     sudo ./trace-cmd report trace.dat
step 4: disable ucode trace timer
     "echo 0 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"

use "ucode_tracing" debugfs file to display number of event
queue wrapped when driver attempt the continuous event logging. If event
queue being wrapped more than once when driver has opportunity to log
the event; it indicated there are events missing in the event log trace.

This continuous event log function only available for 4965 and newer
NICs.

The payload alignment warning enabled by MAC80211_DEBUG_PACKET_ALIGNMENT is
difficult. To fix it, a firmware change is needed but in most cases that's
very difficult. So the benefit from the warning is low and most probably
it just creates more confusion for people who just enable all warnings
(like it did for me).

Remove the unaligned IP payload warning and the kconfig option. But
leave the unaligned packet warning, it will be enabled with
