Please pull this batch of fixes intended for the 3.17 stream:
For the mac80211 bits, Johannes says:
"Two more fixes for mac80211 - one of them addresses a long-standing
issue that we only found when using vendor events more frequently;
the other addresses some bad information being reported in userspace
that people were starting to actually look at."
For the iwlwifi bits, Emmanuel says:
"I re-enable scheduled scan on firmware that contain the fix for
the bug that Linus reported. A few trivial fixes: endianity issues,
the same DTIM period fix that I did in mac80211. Eyal fixes a few
issues we identified with EAPOL, we now send them just as if they were
management frames, this solves interrop issues. Johannes has another
set of trivial fixes, while Luca fixes the way we configure the filters
in the firmware. Last but not least, a new device is added by Oren."
Emmanuel was traveling, resulting in his pull to be a bit larger than
I would have liked to see at this point. FWIW, I have asked Emmanuel
to be much more strict for any more pull requests in this cycle.
In addition to the above, Sujith Manoharan reverts an earlier ath9k
patch. The earlier change was found to allow for the device to sleep
too long and miss beacons.

This patch changes the logic in tx path to ensure that tx descriptors

Signed-off-by: Beniamino Galvani <b.galvani@gmail.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
In the current implementation the cleaning of tx ring is done by the
NAPI poll handler, which is scheduled after rx interrupts. Thus, in
absence of received packets the reclaim of used tx buffers is never
executed, blocking further transmission.
This can be easily reproduced starting the transmission of a UDP flow
with iperf, which blocks almost immediately because skbs are not
returned to the stack and the socket send buffer becomes full.
The patch enables tx interrupts so that the tx reclaim is scheduled
after completed transmissions.

This reverts commit 09ebb81092.
ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with
the beacon interval. Before this commit, the sleepduration was
never greater than the beacon interval. But now, the behavior
has changed. For example, with an AP that uses a beacon interval of 100:
ath: phy9: next beacon 61128704
ath: phy9: beacon period 204800
ath: phy9: DTIM period 204800
If the sleepduration is calculated based on the listen time, then
the bmiss threshold should also be changed since the HW would
be in sleep state for a longer time, but that is not done currently.
To avoid configuring a higher beacon interval based on the sleepduration,
revert to the original behavior. Power consumption is not a
problem since PS is disabled in ath9k anyway.

The sunvnet driver does not have an rmb() in the ring consumer corresponding
to the wmb() in the producer. According to Documentation/memory-barriers.txt:
"When dealing with CPU-CPU interactions, certain types of memory barrier should
always be paired. A lack of appropriate pairing is almost certainly an error."
In cases where an rmb() is not a no-op and a consumer is removing data from
the ring while a producer is adding new entries, a load reorder would allow
CPU1 CPU2
---- ----
LOAD desc.size [e.g]
STORE desc.size
<wmb>
set desc.hdr.state = VIO_DESC_READY
LOAD desc.hdr.state
[because VIO_DESC_READY, use
old desc.size, already loaded
out of order]
[CPU2 has reordered apparently unrelated LOADs]
To ensure other desc fields are not loaded before checking VIO_DESC_READY, we
need an rmb() between the check and desc data accesses.
I've also moved the viodbg() call to after the rmb() so that it, too, has
current descriptor data even with reordering, which has the side effect that
it won't print anything for descriptors that are not VIO_DESC_READY as before.
That's a) probably a good thing, since the fields are not necessarily set and,
b) better than adding another rmb() just for viodbg().
This would not be possible if strict-ordering is enforced, but then the
memory barriers should be no-ops in that case.

Using the LQ table which is initially set according to
the rssi could lead to EAPOLs being sent in high legacy
rates like 54mbps.
It's better to avoid sending EAPOLs in high rates as it reduces
the chances of a successful 4-Way handshake.
Avoid this and treat them like other mgmt frames which would
initially get sent at the basic rate.

This patch does not affect the 10/100 GRETH MAC.
Before all GBit GRETH TX descriptor ring cleaning was done in
start_xmit(), when descriptor list became full it activated
TX interrupt to start the NAPI rx poll function to do TX ring
cleaning.
With this patch the TX descriptor ring is always cleaned from
the NAPI rx poll function, triggered via TX or RX interrupt.
Otherwise we could end up in TX frames being sent but not
reported to the stack being sent. On the 10/100 GRETH this
is not an issue since the SKB is copied&aligned into private
buffers so that the SKB can be freed directly on start_xmit()
