ath5k: Enable AP mode
After some debuging we were hitting the following bugs so far...
* Due to huge channel list hostapd couldn't get infos from the driver
and couldn't set the channel. If we manualy set the channel after
hostapd starts (by setting channel to 0 -auto), beacons are sent
but they wont show up on scan because they are malformed (they have
channel = 0 because hostapd doesn't update the channel info -this is
probably a hostapd bug so i'm CCing Jouni) and they get dropped. Bob
fixed this by only allowing standard channels to be registered so
now hostapd works as expected.
* Docs (and HAL source) say that we must write 0 on timer0 when
operating on AP mode to start TSF increment but this seems to
mess with DBA in many cases and beacon queue never gets started.
We fixed that on the previous patch.
We have some more things to deal with...
* For some reason (hw bug or something else) after restarting hostapd
a few times, beacon inteval seems to change from 100ms to a sec
(we get one beacon per sec).
* We need to set sleep timers on STA mode and enable power saving +
support PCF.
...but i think it's time we enable AP support "officialy" so that
we can get more feedback from users. I ran ath5k with the mentioned
patches + hostapd 0.6.8 and AP mode worked fine (it had some less
throughput on my tests than IBSS but it worked).

* Write next beacon timer even on AP mode since without this we get
no beacons + ath9k does it too. Docs say that we must write 0 on
this register on AP mode to start TSF increment, we do both to be
on the safe side.
* Fix num_tx_pending function, we never read the register :P that's
why we got all those "beacon queue 7 didn't stop messages".
* Put full prioriy on beacon queue, lock all queues with lower
priority using the arblock and also bypass any arblock by seting
the arblock ignore flag.
* For the CAB queue (do we need this thing ?, it seems crap) since
it's supposed to fire up after each beacon (we don't use it on driver
part, ath9k/MadWiFi does), don't make it DBA gated but instead make
it fire after each beacon by using the beacon sent gated flag.
* Increase bmiss threshold to 10, that's what we used on MadWiFi for
a long time. Also when we have pending frames on the beacon queue (we
got a beacon that didn't make it on the air) it's more likely that
the beacon queue never started, probably due to faulty DBA setting,
so change that "beacon queue didn't stop" message.

mac80211: tell driver when idle
When we aren't doing anything in mac80211, we can turn off
much of the hardware, depending on the driver/hw. Not doing
anything, aka being idle, means:
* no monitor interfaces
* no AP/mesh/wds interfaces
* any station interfaces are in DISABLED state
* any IBSS interfaces aren't trying to be in a network
* we aren't trying to scan
By creating a new function that verifies these conditions and calling
it at strategic points where the states of those conditions change,
we can easily make mac80211 tell the driver when we are idle to save
power.
Additionally, this fixes a small quirk where a recalculated powersave
state is passed to the driver even if the hardware is about to stopped
completely.
This patch intentionally doesn't touch radio_enabled because that is
currently implemented to be a soft rfkill which is inappropriate here
when we need to be able to wake up with low latency.
One thing I'm not entirely sure about is this:
phy0: device no longer idle - in use
wlan0: direct probe to AP 00:11:24:91:07:4d try 1
wlan0 direct probe responded
wlan0: authenticate with AP 00:11:24:91:07:4d
wlan0: authenticated
> phy0: device now idle
> phy0: device no longer idle - in use
wlan0: associate with AP 00:11:24:91:07:4d
wlan0: RX AssocResp from 00:11:24:91:07:4d (capab=0x401 status=0 aid=1)
wlan0: associated
Is it appropriate to go into idle state for a short time when we have
just authenticated, but not associated yet? This happens only with the
userspace SME, because we cannot really know how long it will wait
before asking us to associate. Would going idle after a short timeout
be more appropriate? We may need to revisit this, depending on what
happens.

mac80211: fix probe response processing
Due to the use of a _REQ_DIRECT_PROBE bit, which is
unnecessary (and I wonder why it was done that way),
an interesting situation can arise:
1) we try to probe an access point
2) the AP doesn't response in time
3) we tell userspace that we gave up
4) the AP suddenly responds
5) we auth/assoc with the AP
I've seen 4) happen in testing with hostapd SIGSTOPped,
and when SIGCONTinued it processes the probe requests
that came in and send responses. But 5) is not supposed
to happen after we tell everybody we've given up on the
AP.
To fix this, remove the _REQ_DIRECT_PROBE request bit,
and process probe responses when we're in the relevant

are added to call the scanning code whenever necessary. The
scan deferring is changed to simply queue the scanning work
instead of trying to start the scan in place, the scanning work
will then take care of the rest.
Also, currently when internal scans are requested for an interface
that is trying to associate, we reject such scans. This was not

tcp: extend ECN sysctl to allow server-side only ECN
This should be very safe compared with full enabled, so I see
no reason why it shouldn't be done right away. As ECN can only
be negotiated if the SYN sending party is also supporting it,
somebody in the loop probably knows what he/she is doing. If
SYN does not ask for ECN, the server side SYN-ACK is identical
to what it is without ECN. Thus it's quite safe.
The chosen value is safe w.r.t to existing configs which
choose to currently set manually either 0 or 1 but
silently upgrades those who have not explicitly requested
ECN off.
Whether to just enable both sides comes up time to time but
unless that gets done now we can at least make the servers
aware of ECN already. As there are some known problems to occur
if ECN is enabled, it's currently questionable whether there's
any real gain from enabling clients as servers mostly won't
support it anyway (so we'd hit just the negative sides). After
enabling the servers and getting that deployed, the client end
enable really has some potential gain too.

net: Fix skb_tx_hash() for forwarding workloads.
When skb_rx_queue_recorded() is true, we dont want to use jash distribution
as the device driver exactly told us which queue was selected at RX time.
jhash makes a statistical shuffle, but this wont work with 8 static inputs.
Later improvements would be to compute reciprocal value of real_num_tx_queues
to avoid a divide here. But this computation should be done once,
when real_num_tx_queues is set. This needs a separate patch, and a new
field in struct net_device.

My patch incorrectly assumed skb->sk was always valid, but for
"frag_listed" skbs we can only use skb->sk of their parent.
