54bc3a0d7a mwl8k: allow for different receive descriptor formats
As the receive descriptor format is determined by the firmware running
on the hardware and not by the hardware itself, and as these
descriptor formats vary a bit between different firmware releases,
abstract out the receive descriptor init/refill/process methods, and
allow choosing between different formats at run time depending on the
chip and firmware we're running on.

788838ebe8 mwl8k: use pci_unmap_addr{,set}() to keep track of unmap addresses on rx
Instead of reading back the unmap address from the receive
descriptor when doing receive processing, use DECLARE_PCI_UNMAP_ADDR
and pci_unmap_addr{,set}() to keep track of these addresses.

eae74e6545 mwl8k: handle loading AP firmware images
AP and STA firmware images provide a different signature in the

45a390ddd7 mwl8k: change pci id table driver data to a structure pointer
To prepare for adding support for more device types, introduce a
new structure, mwl8k_device_info, where per-device information can
be stored, and change the pci id table driver data from an integer
indicating only the part number to a pointer to a mwl8k_device_info
structure.

Subject: BUG: oops when "rmmod ipw2200"

This happened on wireless-testing v2.6.32-rc6-41575-g5e68bfb. I
modprobed ipw2200, put it into monitor mode, used tshark a while to
monitor, then I stopped tshark, "ifconfig eth2 down" and finally
"rmmod ipw2200", and voila:

37b12dd2b0 rtl8187: Fix kernel oops when device is removed when LEDS enabled
As reported by Rick Farina (sidhayn@gmail.com), removing the RTL8187
USB stick, or unloading the driver rtl8187 using rmmod will cause a
kernel oops.  There are at least two forms of the failure, (1) BUG:
Scheduling while atomic, and (2) a fatal kernel page fault. This
problem is reported in Bugzilla #14539.

This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2,
thus it is technically a regression; however, bisection did not locate
any faulty patch. The fix was found by comparing the faulty code in
rtl8187 with p54usb.  My interpretation is that the handling of work
queues in mac80211 changed enough to the LEDs to be unregistered
before tasks on the work queues are cancelled. Previously, these
actions could be done in either order.

(Herton Ronaldo Krzesinski <herton@mandriva.com.br> reports that the
code is the same in 2.6.31, so this may be a candidate for 2.6.31.x.

cause us grief later on.

For now continue exporting the old API in form
of ieee80211_find_sta_by_hw(), but discourage

77165d8809 mwl8k: enforce FIF_BCN_PRBRESP_PROMISC when no STA interfaces are active
When FIF_BCN_PRBRESP_PROMISC is not set, we enable the hardware's BSS
filter so that we'll only see packets destined for our BSS.  But if no
STA interfaces have been configured, we would end up passing the BSSID
00:00:00:00:00:00 into the POST_SCAN command, which actually disables
the hardware's BSS filter, as it's not a valid BSSID.

Fix this by passing in 01:00:00:00:00:00 instead (the criterion is
that the OUI part of the BSSID must be nonzero), and add comments to
explain what PRE_SCAN and POST_SCAN do.

Minor changes to the transmit quiescing logic:
- Clarify the locking rules for ->tx_wait: only the holder of fw_mutex
  can wait for the TX path to become idle, but tx_wait itself is read
  and cleared by the TX reclaim tasklet under tx_lock.
- Inline mwl8k_txq_busy() in its callers.
- There's no need to kick the transmitter again in
  mwl8k_tx_wait_empty(), since it will have been kicked when the
  packets currently in the TX ring were added to it.
- If the TX ring didn't drain in time, run mwl8k_scan_tx_ring() after

The iwmc3200 has a quirk where retrying SDIO enable during the probe()
path causes bad interactions with the TOP function controller that
causes a reset storm. The workaround is simply not to retry an SDIO
enable in said path (and still do in the reset / reinitialization
paths).

The driver does so by checking i2400ms->debugfs_dentry to see if it
has been initialized; if not, it is in the probe() path. Document said
fact in i2400ms->debugfs_entry.

5ab5a7215a wimax/i2400m: fix device getting stuck in IDLE mode
The i2400m, when conected, will negotiate with the WiMAX basestation
to put the link in IDLE mode when it is not being used. Upon RX/TX
traffic, the link has to be restablished and that might require some
crypto handshakes and maybe a DHCP renew.

This process might take up to 20 (!) seconds and in some cases we were
seeing network watchdog warnings that weren't needed.

So the network watchdog timeout is updated to be slightly above that
20s threshold. As well, the driver itself will double check if the
device is stuck in IDLE mode -- if that happens, the device will be
reset (in this case the queue is also woken up to remove bogus--once
the device is reset--warnings).

c931ceeb78 wimax/i2400m: introduce i2400m_reset(), stopping TX and carrier
Currently the i2400m driver was resetting by just calling
i2400m->bus_reset(). However, this was missing stopping the TX queue
and downing the carrier. This was causing, for the corner case of the
driver reseting a device that refuses to go out of idle mode, that a
few packets would be queued and more than one reset would go through,
making the recovery a wee bit messy.

To avoid introducing the same cleanup in all the bus-specific driver,
introduced a i2400m_reset() function that takes care of house cleaning
and then calling the bus-level reset implementation.

The bulk of the changes in all files are just to rename the call from
i2400m->bus_reset() to i2400m_reset().

32e5a8d651 tg3 / broadcom: Add code to disable rxc refclk
The 5785 does not use the RXC reference clock.  Turning it off is
desirable as it saves power.

By default, the 50610 enables the RXC reference clock and the 50610M
disables it.  Presumably this is one of the reasons why the hardware
architect chose one over the other.

Adding a "rx reference clock disable" flag is not the ideal way to
describe the option, as it would force the MAC using a 50610M to set
the flag.  Ideally we want the flags to represent opt-in behavior that
deviates from hardware defaults.  Furthermore, the lack of a
"disable" flag implies that the requester wants the rx reference clock
enabled, which doesn't necessarily follow.

By presenting the option as a passive statement (rx reference clock
unused) rather than a command, I hope to convey an opt-in option to
disable the rx reference clock that falls back to hardware defaults if
not set.  A secondary benefit of this is that it keeps the
intelligence about phy defaults in the broadcom module where it belongs
and allows the broadcom module more latitude should a bug arise.

88521364cc iwlwifi: remove power-wasting calls to apm_ops.init()
To save power, don't run apm_ops.init() until needed at "up" time.

EEPROM (5000 and earlier devices) may be read without running apm_ops.init(),
but OTP reads (6000 and newer devices) require a powered-up chip.
Therefore, remove apm_ops.init() from the general path in XXXX_pci_probe(),
and call it only if device uses OTP.  Once done with OTP read, call
apm_ops.stop() to reset chip and save power until "up" time comes around.

NOTE:  This patch depends on removal of priv->lock from iwl_apm_stop();
lock does not get initialized until later in flow.  See patch

86c34fe89e libertas: remove internal buffers from GSPI driver
This patch removes the internal command and data buffers that the GSPI driver
maintained and instead relies on the Libertas core to synchronize access
to the command and data ports as with the other interface drivers.  This
cleanup reduces the GSPI driver's memory footprint and should improve
performance by removing the need to copy to these internal buffers.
This also simplifies the bottom half of the interrupt handler.

This is an incremental cleanup: after removing the redundant buffers, we
can further improve the driver to use a threaded IRQ handler instead of
maintaining its own thread.  However I would like a few folks to test
the buffer removal first and make sure that I'm not introducing
regressions.

Tested on Blackfin BF527 with DMA disabled due to an issue with the SPI
host controller driver in the current bleeding-edge Blackfin kernel.  I
would appreciate it if someone with working DMA could test this patch
and provide feedback.

for orientation sensitivity. This was only partially implemented
with the ath9k_hw_decrease_chain_power() but first -- this was being

missing the actual orientation code.

We now ensure to only enable force bias only for AR5416 and BUG_ON()
on other chipsets. Although ath9k_hw_decrease_chain_power() was enabled
for newer chipsets I suspect that it never ran unless the EEPROM had
ATH9K_ANT_FIXED_A or ATH9K_ANT_FIXED_B for antenna diversity.

574d6b122d ath9k_hw: simplify rf attach and rename to ath9k_hw_rf_alloc_ext_banks()
ath9k_hw_rfattach() was just calling a helper and this helper was
doing nothing for single-chip devices, and for non single-chip devices
it is just allocating memory for banks to program the RF registers
at a later time. Simplify this by having the hw initialization call
the rf bank allocation directly for external radios.

Also, propagate an -ENOMEM properly now upon failure.

131d1d036a ath9k_hw: start documenting 802.11n RF anlong front ends
Document what we can about the RF analog front ends (radios)
of Atheros 802.11n devices. What should be clearer now is the
what we do for old pre AR5416 and AR5418 MAC based devices in
comparison to the modern sigle-chip 802.11n solutions.

All devices after AR9280 are single chip and require less
programming -- the RF registers no longer need to be initialized
as they all have the RF analog front end embedded together with
the MAC/BB; this includes the AR9271. Older devices such as the
ones with the AR5416 MACs (PCI) or AR5418 MACs (PCI-E) have an
external 2.4 GHz AR2133 radio or a dual band 2.4 GHz / 5 GHz
AR5133 radio. These external radios require additional programming
of the RF registers.

Clarify which parts are for what devices and which code is
shared. This patch has no functional changes.

8564328d85 ath9k_hw: update register initialization/reset values for ar9271
This update the register initialization/reset values (aka initvals)
for ar9271 based on the last recommended values on 2009-06-04 by our
systems engineering team.

The changes account for:

  * Supporting ar9271 1.0 and ar9271 1.1 together, the difference
    is bb_spectral_scan_ena, for 1.0 we'll set this to 0x1.

  * Ensuring we get the correct noise floor values -115 ~ -118
    when we enable bb_enable_ant_div_lnadiv=0 and
    mc_tx_def_ant_sel=1. Previous to this we would get noise
    floor values in the range -50 ~ -80. To fix settings for
    the registers:

     - bb_ch1_xatten1_db
     - bb_ch1_xatten2_db
     - bb_ch1_xatten1_margin
     - bb_ch1_xatten2_margin
     - bb_ch1_gain_force
     - bb_ch1_xatten2_hyst_margin
     - bb_ch1_xatten1_hyst_margin
     - bb_ch1_max_oc_gain

  * 0x8120[2] mc_mic_new_location_enable is changed to 0x1. The MAC team
    suggest to set this value.

  * 0x9910[0] bb_spectral_scan_ena is changed to 0x0.
    For ar9271 1.1 we don't need to enable this bit.

0869aea0eb mac80211: remove RX_FLAG_RADIOTAP
While there may be a case for a driver adding its
own bits of radiotap information, none currently
does. Also, drivers would have to copy the code
to generate the radiotap bits that now mac80211
generates. If some driver in the future needs to
add some driver-specific information I'd expect
that to be in a radiotap vendor namespace and we
can add a different way of passing such data up
and having mac80211 include it.

Additionally, rename IEEE80211_CONF_RADIOTAP to
IEEE80211_CONF_MONITOR since it's still used by
b43(legacy) to obtain per-frame timestamps.

The purpose of this patch is to simplify the RX
code in mac80211 to make it easier to add paged
skb support.

e9024a059f libertas if_usb: Fix crash on 64-bit machines
On a 64-bit kernel, skb->tail is an offset, not a pointer. The libertas
usb driver passes it to usb_fill_bulk_urb() anyway, causing interesting
crashes. Fix that by using skb->data instead.

This highlights a problem with usb_fill_bulk_urb(). It doesn't notice
when dma_map_single() fails and return the error to its caller as it
should. In fact it _can't_ currently return the error, since it returns
void.

So this problem was showing up only at unmap time, after we'd already
suffered memory corruption by doing DMA to a bogus address.
