Randy fixes a few issues in iwlwifi's Kconfig. Because of
this, 'Debugging options' was not indented under iwlwifi
using menuconfig.
I added a few other fixes on the way, like the link to the
website and added 7265 in the supported NICs.

Add some missing ops and prepare for new devices support. This patch is
a great stability improvement for BCM43217. Earlier Tenda W322E used to
disconnect every 2 minutes (16 times over 30 minutes). With this fix I
got it running for 4 hours (with iperf) without any disconnection.

In managed mode if the driver is getting a re-associate command
from cfg80211, driver deauthenticates with the AP internally and
sends a disconnected event to cfg80211 before completion of its
association process. The disconnected event then modifies the
SSID length as wdev->ssid_len = 0. So, upon receiving the connect
result event from driver, cfg80211 is unable to get that BSS from
the device's BSS list and generates the following WARN_ON message.
WARNING: CPU: 0 PID: 857 at net/wireless/sme.c:658
__cfg80211_connect_result+0x3a6/0x3e0 [cfg80211]()
Avoid re-association while the device is already associated to a
network. Also remove the internal deauthentication from the
association path.

Packets originally buffered for the regular hardware tx queues can end
up being transmitted through the U-APSD queue (via PS-Poll or U-APSD).
When packets are dropped due to retransmit failures, the pending frames
counter is not always updated properly.
Fix this by keeping track of the queue that a frame was accounted for in
the ath_frame_info struct, and using that on completion to decide
whether the counter should be updated.
This fixes some spurious transmit queue hangs.

The tx ring index was immediately trimmed with a
bitmask. This discarded the 0xFFFFFFFF error case
(which theoretically can happen when a device is
abruptly disconnected) and led to using an invalid

If firmware probing worker failed it called
device_release_driver() which synchronously called
remove() pci callback. The callback in turn waited
for the worker that called it to finish resulting
in a deadlock.
Waiting for a completion instead of a worker, like
some other drivers do, doesn't seem like the best
idea either:
Syscall Worker
probe_fw()
rmmod
dev_lock()
pci->remove()
wait_for_completion()
complete_all()
device_release_driver()
dev_lock()
[sleep]
free(ar)
dev_unlock()
[resume]
There's no guarantee that Worker upon resuming can
still access any data/code of the module.
Leaving device bound to a driver is not as harmful
as deadlocking so remove the call to
device_release_driver() while a proper solution is
figured out.

The functionality defined through these flags were actually firmware features
which can change between firmware versions. To make it possible to support
different firmware versions with the same driver, convert the flags to firmware
feature flags.
For backwards compatibility support for old ar6004 firmware FW
API 3 or smaller images we forcefully set the feature bits in the driver.
Starting from FW API 5 the firmware image needs to set them.
