When rx_streaming.interval is non-zero, use automatic rx streaming.
Enable rx streaming on the each rx/tx packet, and disable it
rx_streaming.duration msecs later.
When rx_streaming.always=0 (default), rx streaming is enabled only
when there is a coex operation.

wl12xx supports the "rx streaming" feature:
When in ps mode, and @timeout msecs have been passed since
the last rx/tx, it issues trigger packets (QoS-null/PS-Poll packets,
according to the ac type) in const intervals (in order to reduce
the rx time).

Two functions in ssb are using register_pci_controller() which is
__devinit. The functions ssb_pcicore_init_hostmode() and
ssb_gige_probe() should also be __devinit.
This fixes the following warning:
WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller()
The function ssb_pcicore_init_hostmode() references
the function __devinit register_pci_controller().
This is often because ssb_pcicore_init_hostmode lacks a __devinit
annotation or the annotation of register_pci_controller is wrong.
WARNING: vmlinux.o(.text+0x273398): Section mismatch in reference from the function ssb_gige_probe() to the function .devinit.text:register_pci_controller()
The function ssb_gige_probe() references
the function __devinit register_pci_controller().
This is often because ssb_gige_probe lacks a __devinit
annotation or the annotation of register_pci_controller is wrong.

The patch adds a callback to ath9k_platform_data. If the
callback is provided by the platform code, then it can be
used to hard reset the WMAC device.
The callback is required for doing a hard reset of the AR9330

The AR9330 1.0 and 1.1 are using the same revision,
thus it is not possible to distinguish the two chips.
The platform setup code can distinguish the chips based

to allow getting the revision number from the platform code.

Use the new consistent dump feature from (generic) netlink
to advertise when dumps are incomplete.
Readers may note that this does not initialize the
rdev->bss_generation counter to a non-zero value. This is
still OK since the value is modified only under spinlock
when the list is modified. Since the dump code holds the
spinlock, the value will either be > 0 already, or the
list will still be empty in which case a consistent dump
will actually be made (and be empty).

As USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS, beacon interrupt
(CR_INTERRUPT) might be lost. Problem is that when device trigger CR_INTERRUPT
it disables HW interrupt. Now if USB_INT_ID_REGS with CR_INTERRUPT gets lost,
beacon interrupt stays disabled until beacon watchdog notices the stall. This
happen very often on heavy TX. Improve watchdog to trigger earlier, after three
missing beacon interrupts.

zd_mac_config_beacon() has only limited time to set up beacon when called from
beacon interrupt handler/worker. So do not let it retry acquiring beacon fifo
semaphore in interrupt handler. Beacon fifo semaphore should not be locked by
firmware anyway at this time, it's only locked when device is using/txing
beacon.

Device losses read-reg interrupts. By looking at usbmon it appears that
USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS. This causes read
command to timeout, usually under heavy TX.
Fix by retrying read registers again if USB_INT_ID_RETRY_FAILED is received
while waiting for USB_INT_ID_REGS.
However USB_INT_ID_REGS is not always lost but is received after
USB_INT_ID_RETRY_FAILED and is usually received by the retried read
command. USB_INT_ID_REGS of the retry is then left unhandled and might
be received by next read command. Handle this by ignoring previous
USB_INT_ID_REGS that doesn't match current read command request.

Driver uses IEEE80211_HW_SIGNAL_UNSPEC and so signal values reported to
mac80211 should be in range 0..100. Sometimes device return out of range
values. These out of range values can then trigger warning in
cfg80211_inform_bss_frame.
This patch adds checks to enforce range returned from driver to
mac80211 be in 0..100 range.

Consider the following situation:
* a dump that would show 8 entries, four in the first
round, and four in the second
* between the first and second rounds, 6 entries are
removed
* now the second round will not show any entry, and
even if there is a sequence/generation counter the
application will not know
To solve this problem, add a new flag NLM_F_DUMP_INTR
to the netlink header that indicates the dump wasn't
consistent, this flag can also be set on the MSG_DONE
message that terminates the dump, and as such above
situation can be detected.
To achieve this, add a sequence counter to the netlink
callback struct. Of course, netlink code still needs
to use this new functionality. The correct way to do
that is to always set cb->seq when a dumpit callback
is invoked and call nl_dump_check_consistent() for
each new message. The core code will also call this
function for the final MSG_DONE message.
To make it usable with generic netlink, a new function
genlmsg_nlhdr() is needed to obtain the netlink header
from the genetlink user header.
