When CONF_AUTO_SET_IO or CONF_AUTO_SET_IOMEM are set, the corresponding
fields in struct pcmcia_device *p_dev->resource[0,1,2] are set
accordinly. Drivers wishing to override certain settings may do so in
the callback function, but they no longer need to parse the CIS entries
stored in cistpl_cftable_entry_t themselves.

Introduce an autoconfiguration feature to set certain values in
pcmcia_loop_config(), instead of copying the same code over and over
in each PCMCIA driver. At first, introduce the following options:

CONF_AUTO_CHECK_VCC	check or matching Vcc entry
CONF_AUTO_SET_VPP	set Vpp
CONF_AUTO_AUDIO		enable the speaker line

IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO
(all other drivers). As this flags seems to relate to ioport access, make
it conditional to the driver having requested IO port access. There are two
drivers which do not request IO ports, but did set INT_MEMORY_AND_IO:
ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

When uCode error condition detected, driver try to perform either
rf reset or firmware reload in order bring device back to
working condition.

If rf reset is required and scan is in process, there is no need
to issue rf reset since scan already reset the rf.

If firmware reload is required and scan is in process, skip the
reload request. There is a possibility firmware reload during
scan cause problem.

The 5 GHz CTL indexes were not being read for all hardware
devices due to the masking out through the CTL_MODE_M mask
being one bit too short. Without this the calibrated regulatory
maximum values were not being picked up when devices operate
on 5 GHz in HT40 mode. The final output power used for Atheros
devices is the minimum between the calibrated CTL values and
what CRDA provides.

prevented the 5 GHz CTL indexes from being used, which are
stored towards the end of the EEPROM block. This fix allows

Michael reported that p54* never really entered power
save mode, even tough it was enabled.

It turned out that upon a power save mode change the
firmware will set a special flag onto the last outgoing
frame tx status (which in this case is almost always the
designated PSM nullfunc frame). This flag confused the
driver; It erroneously reported transmission failures
to the stack, which then generated the next nullfunc.
and so on...

Atheros PCIe wireless cards handled by ath5k do require L0s disabled.
For distributions shipping with CONFIG_PCIEASPM (this will be enabled
by default in the future in 2.6.36) this will also mean both L1 and L0s
will be disabled when a pre 1.1 PCIe device is detected. We do know L1
works correctly even for all ath5k pre 1.1 PCIe devices though but cannot
currently undue the effect of a blacklist, for details you can read
pcie_aspm_sanity_check() and see how it adjusts the device link
capability.

It may be possible in the future to implement some PCI API to allow
drivers to override blacklists for pre 1.1 PCIe but for now it is
best to accept that both L0s and L1 will be disabled completely for
distributions shipping with CONFIG_PCIEASPM rather than having this
issue present. Motivation for adding this new API will be to help
with power consumption for some of these devices.

Example of issues you'd see:

  - On the Acer Aspire One (AOA150, Atheros Communications Inc. AR5001
    Wireless Network Adapter [168c:001c] (rev 01)) doesn't work well
    with ASPM enabled, the card will eventually stall on heavy traffic
    with often 'unsupported jumbo' warnings appearing. Disabling
    ASPM L0s in ath5k fixes these problems.

  - On the same card you would see a storm of RXORN interrupts
    even though medium is idle.

Credit for root causing and fixing the bug goes to Jussi Kivilinna.

Some APs advertise that they may be HT40 capable in the capabilites
but the current operating channel configuration may be only HT20.
This causes disconnection as ath9k_htc sets WLAN_RC_40_FLAG despite
the AP operating in HT20 mode.
Hence set this flag only if the current channel configuration
is HT40 enabled.

Since it can be changed via sysfs, we need to make a copy.  This most

Currently the driver will try to protect all frames,
which leads to a lot of odd things like sending an
RTS with a zeroed RA before multicast frames, which
is clearly bogus.

In order to fix all of this, we need to take a step
back and see what we need to achieve:
 * we need RTS/CTS protection if requested by
   the AP for the BSS, mac80211 tells us this
 * in that case, CTS-to-self should only be
   enabled when mac80211 tells us
 * additionally, as a hardware workaround, on
   some devices we have to protect aggregated
   frames with RTS

To achieve the first two items, set up the RXON
accordingly and set the protection required flag
in the transmit command when mac80211 requests
protection for the frame.

To achieve the last item, set the rate-control
RTS-requested flag for all stations that we have
aggregation sessions with, and set the protection
required flag when sending aggregated frames (on
those devices where this is required).

Since otherwise bugs can occur, do not allow the
user to override the RTS-for-aggregation setting
from sysfs any more.

Finally, also clean up the way all these flags get
set in the driver and move everything into the
device-specific functions.

spin_is_locked() can return zero on some (UP?)
configurations because locks don't exist, and
that causes an endless amount of warnings. Use
lockdep_assert_held() instead, which has two
advantages:
 1) it verifies the current task is holding
    the lock or mutex
 2) it compiles away completely when lockdep
    is not enabled

Fix this leftover TODO from the cfg80211 conversion by doing a scan
if cfg80211 didn't pass in the BSSID for us.  Since the scan code
uses so much of the cfg80211_scan_request structure to build up the
firmware command, we just fake one when the scan request is triggered
internally.  But we need to make sure that internal 'fake' cfg82011
scan request does not get back to cfg82011 via cfg80211_scan_done().

Some APs get pissy if you don't send the firmware the extended rates
in the association request's rates TLV.  Found this on a Linksys
WRT54G v2; it denies association with status code 18 unless you
add the extended rates too.  The old driver did this, but it got
lost in the cfg80211 conversion.

IRQ and resource[] may not have correct values until
after PCI hotplug setup occurs at pci_enable_device() time.

The semantic match that finds this problem is as follows:

// <smpl>
@@
identifier x;
identifier request ~= "pci_request.*|pci_resource.*";
@@

(
* x->irq
|
* x->resource
|
* request(x, ...)
