Arik Nemtsov b4d38db121 wl12xx: AP-mode - use mac80211 indication about STA WME support
When adding a station, use the information given in the mac80211
populated ieee80211_sta structure to determine if it supports WME.
Provide this information to the FW.

This patch depends on "mac80211: propagate information about
STA WME support down".

Rafał Miłecki bdb2dfb237 b43: HT-PHY: upload PHY values when switching channel
After calibrating radio you can find few PHY writes in MMIO dumps:
 phy_read(0x0009) -> 0x0000
phy_write(0x01ce) <- 0x03dd
phy_write(0x01cf) <- 0x03d9
phy_write(0x01d0) <- 0x03d5
phy_write(0x01d1) <- 0x0424
phy_write(0x01d2) <- 0x0429
phy_write(0x01d3) <- 0x042d
By comparing to N-PHY code we found out that they are PHY tables for
channel switching plus band info read at the beginning.

Rajkumar Manoharan f6b4e4d476 ath9k: Fix locking issue during tx completion
The received tx status of aggregated frame without BlockAck may
cause deaf state in AR5416 cards. So the driver does a reset to
recover. When this happens, we release the pcu_lock before doing
a reset as ath_rest acquires pcu_lock. This is ugly and also not
atomic. Fixing this addresses the TX DMA failure also.

ath_tx_complete_aggr can be called from different paths which
takes different variants of spin_lock. This patch also addresses
the following warning.

Rajkumar Manoharan dcfcbd590d ath9k_hw: Fix false tx hung detection in AR9003 chips
The edma based (AR9003 family) chips update tx status
descriptors in a common ring buffer for all transmitted
frames. Whenever tx interrupt is raised, the descriptors
are processed and tx status index is moved.

The complete tx stauts ring are updated with beacons tx status
when there are no data frames to be sent for a period of time.
In this state, transmitting data frames causes the driver to
wait for the tx status on an incorrect tx status index though
the status was updated by hw properly. The driver detects this
condition as a h/w hang and does unnecessary chip resets.

This issue was orginally reported in adhoc mode while sending
frames after an idle time.

which is obviously wrong, the user should not see the *_UCODE_API_MAX
macros but the actual ucode API versions here.

The problem are the
    #define *_MODULE_FIRMWARE(api) *_FW_PRE #api ".ucode"
which do not expand api correctly (because this is a macro itself).

Fixed by using __stringify() from linux/stringify.h.

Ido Yariv 95dac04f88 wl12xx: Support routing FW logs to the host
A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).

There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
   buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
   path.

Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.

A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.

P2P interfaces must not use CCK rates, only OFDM
rates are allowed. To set this up, we need to set

of starting with 1M.

Since the interface type can change, also reset
the broadcast station when RXON changes.

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()

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.

Jussi Kivilinna dde4673b8d zd1211rw: don't let zd_mac_config_beacon() run too long from beacon interrupt handler
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.

Jussi Kivilinna c900eff30a zd1211rw: handle lost read-reg interrupts
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.

Jussi Kivilinna 7a1d6564a1 zd1211rw: fix invalid signal values from device
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.

force reset device during probe.

Emmanuel Grumbach 48d1a2110a iwlagn: add a iwl_pci.[ch] files that will contain all PCI specific code
Move some PCI functionality to the new iwl_pci.[ch] files:
* the PCI_DEVICE_TABLE
* the pci_driver struct definition
* the PCI probe / remove functions
* the PCI suspend / resume functions

All these functions are now split: the trigger comes from the PCI layer which
calls to the bus generic code located in the other files.

This is the beginning only. There are still a lot of PCI related code needs
to be gathered.

It is superfluous to disable the interrupts after we reset the NIC. The only
entity that could enable the interrupts after the NIC is reset is the driver.
