The sky2 driver combines auto speed negotiation with automatic negotiation
of pause parameters; but the ethtool interface expects them to be
split. This patch allows autonegotiation to be used for speed, but
manually disable flow control.

Transmit completion can safely run lockless against transmit start.
In the normal case, completion is done from NAPI and only looks
at elements that are at the tail of the ring. When doing shutdown
or reset, the transmiter should be completely block by NAPI disable
and blocking of transmit queue.
Based on earlier work by Mike McCormack.

This unifies the places that bounce the device (suspend/resume
and restart). And makes the operations have the same semantics
as normal dev_open/dev_stop.
This also avoids setting the multicast addresses twice when
device is brought up.

Avoid any possible problems with accessing PHY registers on shutdown.
This is a purely theoretical issue and is not related to any of the
outstanding bug reports. Since receiver and transmitter are already
shutdown and phy interrupts for this device are already disabled,
there should already be enough protection. Suggested by Mike McCormack.

Reseting the tx chain too soon results in invalid tx queue positions
being delivered in the status queue. This also makes sure there's no
overlap between the cleanup done by sky2_tx_clean() and

ath9k supports the AR9002 family of chipsets. This includes

have AR9280+AR5133).

Sometimes drivers might have a good reason to override
the PS default, like iwlwifi right now where it affects
RX performance significantly at this point. This will
allow them to override the default, if desired, in a
way that users can still change it according to their
trade-off choices, not the driver's, like would happen
if the driver just disabled PS completely then.

If you trigger a scan request on an interface and then
take it down, or rmmod the module or unplug the device
the driver might "forget" to cancel the scan request.
That is a bug in the driver, but the current behaviour
is that we just hang endlessly waiting for the netdev
refcount to become 0 which it never will. To improve
robustness, check for this situation in cfg80211, warn
about it and clean up behind the driver. I don't just
clean up silently because it's likely that the driver
also has some internal state it has now leaked.
Additionally, this fixes a locking bug, clearing the
scan_req pointer should be done under the rdev lock.
Finally, we also need to _wait_ for the scan work and
not just abort it since it might be pending and wanting
to do a cleanup.

Turns out ath5k and ath9k can share the same helper to
allocates RX skbs. We allocate skbs aligned to the cache line
size. This requirement seems to have come from AR5210; when
this was not done it seems sometimes we'd get bogus data. I'm
also told it may have been a performance enhancement
consideration. In the end I can't be sure we can remove this
on new hardware so just keep this and start sharing it through
ath.ko.
Make ath9k start using this, ath5k is next.

The 11s task group recently changed the frame mesh multicast/broadcast frame
format to use 3-address. This was done to avoid interactions with widely
deployed lazy-WDS access points.
This patch changes the format of group addressed frames, both mesh-originated
and proxied, to use the data format defined in draft D2.08 and forward. The
address fields used for group addressed frames is:
In 802.11 header
ToDS:0 FromDS:1
addr1: DA (broadcast/multicast address)
addr2: TA
addr3: Mesh SA
In address extension header:
addr4: SA (only present if frame was proxied)
Note that this change breaks backward compatibility with earlier mesh stack
versions.
