mv643xx_eth: don't include cache padding in rx desc buffer size
If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth
allocates a couple of extra bytes at the start of each receive buffer
to make the data payload end up on a cache line boundary.
These extra bytes are skb_reserve()'d before DMA mapping, so they
should not be included in the DMA map byte count (as the mapping is
done starting at skb->data), nor should they be included in the
receive descriptor buffer size field, or the hardware can end up
DMAing beyond the end of the buffer, which can happen if someone
sends us a larger-than-MTU sized packet.
This problem was introduced in commit
7fd96ce47ff ("mv643xx_eth:
rework receive skb cache alignment", May 6 2009), but hasn't appeared
to be problematic so far, probably as the main users of mv643xx_eth
all have NET_SKB_PAD == L1_CACHE_BYTES.

The mc_loop flag is present in the family specific part of the socket

family mc_loop flag. When the packet is pushed through the L3 tunnel
it will eventually be processed by the outer family which if different

Here is why.
On suspend:
- PM core starts suspending devices, ucc_geth_suspend gets called;
- ucc_geth calls phy_stop() on suspend. Note that phy_stop() is
mostly asynchronous so it doesn't block ucc_geth's suspend routine,
it just sets PHY_HALTED state and disables PHY's interrupts;
- Suddenly the state machine gets scheduled, it grabs the phydev->lock
mutex and tries to process the PHY_HALTED state, so it calls
phydev->adjust_link(phydev->attached_dev). In ucc_geth case
adjust_link() calls msleep(), which reschedules the code flow back to
PM core, which now finishes suspend and so we end up sleeping with
phydev->lock mutex held.
On resume:
- PM core starts resuming devices (notice that nobody rescheduled
the state machine yet, so the mutex is still held), the core calls
ucc_geth's resume routine;
- ucc_geth_resume restarts the PHY with phy_stop()/phy_start()
sequence, and the phy_*() calls are trying to grab the phydev->lock
mutex. Here comes the deadlock.
This patch fixes the issue by stopping the state machine on suspend
and starting it again on resume.

mac80211: fix propagation of failed hardware reconfigurations
mac80211 does not propagate failed hardware reconfiguration
requests. For suspend and resume this is important due to all
the possible issues that can come out of the suspend <-> resume
cycle. Not propagating the error means cfg80211 will assume
the resume for the device went through fine and mac80211 will
continue on trying to poke at the hardware, enable timers,
queue work, and so on for a device which is completley
unfunctional.
The least we can do is to propagate device start issues and
warn when this occurs upon resume. A side effect of this patch
is we also now propagate the start errors upon harware
reconfigurations (non-suspend), but this should also be desirable
anyway, there is not point in continuing to reconfigure a
device if mac80211 was unable to start the device.

mac80211: fix race with suspend and dynamic_ps_disable_work
When mac80211 suspends it calls a driver's suspend callback
as a last step and after that the driver assumes no calls will
be made to it until we resume and its start callback is kicked.
If such calls are made, however, suspend can end up throwing
hardware in an unexpected state and making the device unusable
upon resume.
Fix this by preventing mac80211 to schedule dynamic_ps_disable_work
by checking for when mac80211 starts to suspend and starts
quiescing. Frames should be allowed to go through though as
that is part of the quiescing steps and we do not flush the
mac80211 workqueue since it was already done towards the
beginning of suspend cycle.
The other mac80211 issue will be hanled in the next patch.

It is not clear to me how the first "direct probe" here
happens, but this seems to be a race condition, if the
user requests to deauth after requesting assoc, but before
the assoc response is received. In that case, it may
happen that mac80211 tries to report the assoc success to
cfg80211, but gets blocked on the wdev lock that is held
because the user is requesting the deauth.
The result is that we run into a warning. This is mostly
harmless, but maybe cause an unexpected event to be sent
to userspace; we'd send an assoc success event although
userspace was no longer expecting that.
To fix this, remove the warning and check whether the
race happened and in that case abort processing.

ath5k: fix SWI calibration interrupt storm
The calibration period is now invoked by triggering a software
interrupt from within the ISR by ath5k_hw_calibration_poll()
instead of via a timer.
However, the calibration interval isn't initialized before
interrupts are enabled, so we can have a situation where an
interrupt occurs before the interval is assigned, so the
interval is actually negative. As a result, the ISR will
arm a software interrupt to schedule the tasklet, and then
rearm it when the SWI is processed, and so on, leading to a
softlockup at modprobe time.
Move the initialization order around so the calibration interval
is set before interrupts are active. Another possible fix
is to schedule the tasklet directly from the poll routine,
but I think there are additional plans for the SWI.

This is because ucc_geth_tx() tries to process an empty queue when
queues are logically stopped. Stopping the queues doesn't disable
polling, and since nowadays ucc_geth_tx() is actually called from
the polling routine, the oops above might pop up.
Fix this by removing 'netif_queue_stopped() == 0' check.

mac80211: rework MLME for multiple authentications
inadvertedly broke WMM because it removed, along with
a bunch of other now useless initialisations, the line
initialising sdata->u.mgd.wmm_last_param_set to -1
which would make it adopt any WMM parameter set. If,
as is usually the case, the AP uses WMM parameter set
sequence number zero, we'd never update it until the
AP changes the sequence number.
Add the missing initialisation back to get the WMM
settings from the AP applied locally.

mac80211: fix peer HT capabilities
I noticed yesterday, because Jeff had noticed
a speed regression, cf. bug
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138
that the SM PS settings for peers were wrong.
Instead of overwriting the SM PS settings with
the local bits, we need to keep the remote bits.
The bug was part of the original HT code from
over two years ago, but unfortunately nobody
noticed that it makes no sense -- we shouldn't
be overwriting the peer's setting with our own
but rather keep it intact when masking the peer
capabilities with our own.
While fixing that, I noticed that the masking of
capabilities is completely useless for most of
the bits, so also fix those other bits.
Finally, I also noticed that PSMP_SUPPORT no
longer exists in the final 802.11n version, so
also remove that.

a) unnecessary because the buffer is allocated with kzalloc and is hence

b) for priv->curbssparams.ssid_len == 32, it writes back one byte too
