It looks like there are some issues in the current ath9k version as
far as staggered Beacon frame scheduling is concerned. This results in
Beacon frame timestamp being off by 25 milliseconds or so which can
cause issues with multicast power save buffering in AP mode. Some
client stations fail to receive multicast frames when there is this
large an offset between TBTT and actual Beacon transmission time.
Since ath9k does not yet support multiple BSSes anyway, the staggered
Beacon frame scheduling is just increasing the number of interrupts at
this point. The easiest fix for the timestamp offset is to disable
staggered Beacon frames for now. We need to redesign beacon.c anyway
when adding multi-BSS support with mac80211 since the existing code
depends on different mechanism for Beacon frame transmission.

As reported by Hermann Lauer, PCS PHY support in the sungem
driver simply doesn't work.
When the chip is reset due to open, or some other similar operation,
the PCS is reset too but we don't program it back into a running
state. The result is no link when the device is brought up.
This partially rectifies the situation for the moment, by kicking
the PCS after a sungem chip reset so that it will renegotiate and
be re-enabled again.
The behavior is still a little bit dodgy as the added renegotiate
make the link take some time after bringing the interface up,
but this is a significant improvement in that things actually work
now :-)
Based almost entirely upon an initial patch by Hermann.

Patch does following things
1) This patch fixes the a-band association for passive channels with new
uCode feature that it allows direct scan on passive channels after
auto-switch from passive to active. This enables sending of direct probes
on passive channels, as long as some traffic is detected on that channel.
This improves the scanning for hidden SSIDs in A-band,which is all
passive channels.
This patch fixes the bug no 1748.
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748
2) This fix will only work with uCode version 15.28.2.8 and above.
Prior versions of uCode would work only if we heard the traffic within
active dwell time, which is much shorter than passive dwell time and
is shorter than typical beacon periods. This patch also provids full
active dwell time even if we hear traffic late in passive dwell.
3) uCode API version is incremented to 2.

This patch cleans up key type assignment in ath5k_hw_set_key by

memcpy() calls for extracting key material into the hardware format
with a loop that works regardless of key size.

In "ipw2200: Call netif_*_queue() interfaces properly", netif_stop_queue()
and netif_wake_queue() were removed with the reason
"netif_carrier_{on,off}() handles starting and stopping packet flow into
the driver". The patch also removes a valid condition check that
ipw_tx_skb() cannot be called if device is not in STATUS_ASSOCIATED state.
But netif_carrier_off() doesn't guarantee netdev->hard_start_xmit won't
be called because linkwatch event is handled in a delayed workqueue. This
caused a kernel oops reported by Frank Seidel:
https://bugzilla.novell.com/show_bug.cgi?id=397390

Bring the physical link down when the interface is down by placing the PHY
in power-down state, unless WOL is enabled. This mirrors the behavior of
other drivers including e1000 and tg3.
Without the patch, ifconfig down leaves the physical link up, which confuses
datacenter users who expect the link lights both on the NIC and the switch to
go out when they bring an interface down.
Furthermore, even though the phy is powered on, autonegotiation stops working,
so a normally gigabit link might suddenly become 100 Mbit half-duplex when the
interface goes down, and become gigabit when it comes up again.
Ayaz said:
I would not include this patch until further testing is performed. NVIDIA
MCP chips use 3rd party PHY vendors. By powering down the phy, it could
have adverse affects on certain phys.

The bnx2 chips do not support per MSI vector masking. On 5706/5708, new MSI
address/data are stored only when the MSI enable bit is toggled. As a result,
SMP affinity no longer works in the latest kernel. A more serious problem is
that the driver will no longer receive interrupts when the MSI receiving CPU
goes offline.
The workaround in this patch only addresses the problem of CPU going offline.
When that happens, the driver's timer function will detect that it is making
no forward progress on pending interrupt events and will recover from it.
Eric Dumazet reported the problem.
We also found that if an interrupt is internally asserted while MSI and INTA
are disabled, the chip will end up in the same state after MSI is re-enabled.
The same workaround is needed for this problem.

The function is_pure_response() does "ntohl(var) & const" and then
essentially just tests whether the result is 0 or not; this can be done

Commit 7ff93f8b ("mlx4_core: Multiple port type support") introduced
support for different port types. As part of that support, SET_PORT
is invoked to set the port type during driver startup. However, as a
side-effect, for IB ports the invocation of this command also sets the
port's capability mask to zero (losing the default value set by FW).
To fix this, get the default ib port capabilities (via a MAD_IFC Port
Info query) during driver startup, and save them for use in the
mlx4_SET_PORT command when setting the port-type to Infiniband.
This patch fixes problems with subnet manager (SM) failover such as

We would get an oops on RX on -ENOMEM by passing
NULL to the hardware on ath_rx_buf_link(). The oops
would look something like this:
ath_rx_tasklet+0x515/0x53b
ath9k_tasklet+0x48
tasklet_action
__do_softirq
irq_exit
do_IRQ
RIP: ath_rx_buf_link+0x3a
We correct this by handling the requeue directly on
the ath_rx_tasklet() and trying to allocate an skb
*prior* to sending up the last hardware processed
skb. If we run out of memory this gauranteees we have
skbs to work with while it simply drops new received
frames.

Instead of hardcoding the used in/out endpoints
we should detect them by walking through all

rt2800usb will gain the most out of this, because
the legacy drivers indicate that there are multiple
endpoints available.
However this code might benefit at least rt73usb as
well for the MIMO queues, and if we are really lucky
rt2500usb will benefit because for the TX and PRIO
queues.
Even if rt2500usb and rt73usb do not get better performance

Race condition causes RX buffers to be accessed even before it is

the hardware is registered with mac80211. The mac80211 start callback
is ready to be fired once the device is registered for a case when the
wpa_supplicant is also running at the same time.
The same race condition is also possible for RKFILL registration

The callback function write_tx_data() can only fail
when our ENTRY_OWNER_DEVICE_DATA flag on a queue entry
failed to determine the entry was not available and
it is in fact still owned by the hardware.
This means that if that function fails the queue
must be stopped in mac80211.
When rt2x00queue_get_queue() returns NULL in the TX
path, it means mac80211 has passed us an invalid queue,
although this should be impossible, it shouldn't hurt
if we send mac80211 a signal to stop the queue either.
Both issues can simply be resolved by removing their
manual failure handler and making them use the failure path
provided in rt2x00mac_tx().

rt2500usb and rt73usb have different register word sizes,
for that reason the register access wrappers were never
moved into rt2x00usb.
With rt2800usb on its way, we should favor the 32bit
register access and move those wrappers into rt2x00usb.
That saves duplicate code, since only rt2500usb will
need the special 16bit wrappers.

We should only tell the hardware its capable of DMA'ing
to us only what we asked dev_alloc_skb(). Prior to this
it is possible a large RX'd frame could have corrupted
DMA data but for us but we were saved only because we
were previously also pci_map_single()'ing the same large
value. The issue prior to this though was we were unmapping
a smaller amount which the prior DMA patch fixed.

This should fix the SW-IOMMU bounce buffer starvation
seen ok kernel.org bugzilla 11811:
http://bugzilla.kernel.org/show_bug.cgi?id=11811
Users on MacBook Pro 3.1/MacBook v2 would see something like:
DMA: Out of SW-IOMMU space for 4224 bytes at device 0000:0b:00.0
Unfortunately its only easy to trigger on MacBook Pro 3.1/MacBook v2
so far so its difficult to debug (even with swiotlb=force).
We were pci_unmap_single()'ing less bytes than what we called
for with pci_map_single() and as such we were starving
the swiotlb from its 64MB amount of bounce buffers. We remain
consistent and now always use sc->rxbufsize for RX. While at
it we update the beacon DMA maps as well to only use the data
portion of the skb, previous to this we were pci_map_single()'ing
more data for beaconing than what we tell the hardware it can use,
therefore pushing more iotlb abuse.
Still not sure why this is so easily triggerable on
MacBook Pro 3.1, it may be the hardware configuration
tends to use more memory > 3GB mark for DMA.

I asked around, and he's right, there may be platforms that do not allow
passing such such an address to the DMA API functions. This patch
changes it by using the proper dma_sync_single_range_for_cpu API
invented for this purpose.
