In various cases wl1251_op_bss_info_changed() did not call elp_sleep()
after an error was noticed. Fix it by using correct goto label.
The bug was a theoretical one, in practise it doesn't matter because
if commands start returning errors there will be lots of other problems.

The number of channels to be used in scan was hard coded in wl1251. The
proper way is to use the channels array provided by mac80211.

The current scanning code wasn't following the preferred style. Move code
related to scan and trigger scan to commans to wl1251_cmd.c. Because
there's now less code in wl1251_hw_scan(), the function can be now
merged with wl1251_op_hw_scan().

The callback sets slot time as specified in IEEE 802.11-2007 section

The original code was correct in 802.11a mode only, 802.11b/g uses
different clock rates. The new code uses values taken from FreeBSD HAL
and should be correct for all modes including turbo modes.
The former rate calculation was used by slope coefficient calculation
function ath5k_hw_write_ofdm_timings. However, this function requires
the 802.11a values even in 802.11g mode. Thus the use of
ath5k_hw_htoclock was replaced by hardcoded values. Possibly the slope
coefficient calculation is not related to clock rate at all.

Functions ath5k_hw_get_slot_time and ath5k_hw_set_slot_time were
converting microseconds to clocks only for AR5210, although it's needed
for all supported devices. The conversion was moved outside the
hardware-specific branches.
The original code also limited minimum slot time to 9, while turbo modes
use 6, this was fixed too.

The newer single chip hardware family of chipsets have not been
experiencing issues with power saving set by default with recent
fixes merged (even into stable). The remaining issues are only
reported with AR5416 and since enabling PS by default can increase
power savings considerably best to take advantage of that feature
as this has been tested properly.
For more details on this issue see the bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=14267
We leave AR5416 with PS disabled by default, that seems to require
some more work.

For STA firmware, move the per-peer hardware station ID to the
driver-private part of struct ieee80211_sta, where it belongs.
(Since issuing a hardware station database maintenance command sleeps,
we can't hold a reference to the ieee80211_sta * across the command,
and since we won't know the station ID until after the command
completes, we need to re-lookup the sta when the command is done to
write the returned station ID back to its driver-private part.)

Commit 250cce26d5d03337aec4ff8405121f026adb4a89 uses UTS_RELEASE
as the the in-tree iwlwifi driver version. However the inclusion
of generated/utsrelease.h makes it a unpleasant behaviour to
recompile the driver everytime when utsrelease.h is updated. In
fact, the driver module is already built with the UTS_RELEASE
information via vermagic of modinfo. Mark the in-tree driver
with the version string "in-tree" to distinguish with those old
out-of-tree drivers.

Current rt2x00 drivers may result in a "ieee80211_tx_status: headroom too
small" error message when a frame needs to be properly aligned before
transmitting it.
This is because the space needed to ensure proper alignment isn't
requested from mac80211.
Fix this by adding sufficient amount of alignment space to the amount
of headroom requested for TX frames.

Commit 8bf3d79bc401ca417ccf9fc076d3295d1a71dbf5 enabled EEPROM
checksum checks to avoid bogus bug reports but failed to address
updating the code to consider devices with custom EEPROM sizes.
Devices with custom sized EEPROMs have the upper limit size stuffed
in the EEPROM. Use this as the upper limit instead of the static
default size. In case of a checksum error also provide back the
max size and whether or not this was the default size or a custom
one. If the EEPROM is busted we add a failsafe check to ensure
we don't loop forever or try to read bogus areas of hardware.

I noticed a timeout bug in
/drivers/net/wireless/wl12xx/wl1271_spi.c
In the current code you cannot tell why you exited
the "poll for data ready" do-while loop if exiting
was done after the last possible loop.
Then timeout==0 regardless of (val & OCP_READY_MASK) or
!(val & OCP_READY_MASK), leading to possible false timeout...
Simple correction could be decreasing timeout after checking
for !(val & OCP_READY_MASK), not before
(Manually converted from email to an actual patch by me. -- JWL)

We've long lacked a good confirmation that frames
have really gone out, e.g. before going off-channel
for a scan. Add a flush() operation that drivers
can implement to provide that confirmation, and use
it in a few places:
* before scanning sends the nullfunc frames
* after scanning sends the nullfunc frames, if any
* when going idle, to send any pending frames

It is checked in add_interface, but there it is easily replaced with
a check of priv->vif. If that information should become necessary,
it is available in vif->type anyway.
It is also checked in led_turn_on and led_turn_off, where I made the
substitutions as described above. Of course, these checks seem to
have been incorrect since the driver was using NL80211_IFTYPE_MONITOR
to indicate no interface rather than NL80211_IFTYPE_UNSPECIFIED.
Anyway, I think these checks may be extraneous...?
