This introduces a debugfs file (ieee80211/phy#/hwsim/ps) that can be
used to force a simulated radio into power save mode. Following values
can be written into this file to change PS mode:
0 = power save disabled (constantly awake)
1 = power save enabled (drop all frames; do not send PS-Poll)
2 = power save enabled (send PS-Poll frames automatically to receive
buffered unicast frames); not yet fully implemented
3 = manual PS-Poll trigger (send a single PS-Poll frame)
Two different behavior for power save mode processing can be tested:
- move between modes 1 and 0 (i.e., receive all buffered frames at a
time)
- move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps'
debugfs file) to fetch power save buffered frames one at a time
Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but
eventually, it should take a look at TIM IE and send PS-Poll if a
traffic bit is set for our AID.

mac80211 supports multiple virtual interfaces for a single device. For
example, a managed interface (wlan0) and a monitor interface (mon0) can
exist at the same time. Thus priv->iw_mode is not sufficient to track
the wireless mode any more. The patch redefines priv->iw_mode as the
first interface mode (the same as priv->vif->type if priv->vif != NULL).
If another monitor type interface is created later, we don't change
priv->iw_mode into monitor. This way, the original interface still
works. The patch also requests mac80211 to do reassociation after we
change the Rx filter flags.

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.
OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.
Different to readonly reference of netdev->priv, in this driver, netdev->priv

The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.
Drivers need not do it any more.
Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

If card is using downloadable firmware (like Agere 9.x), firmware has
to be reloaded during resume. It is not possible to use request_firmware
for that, because tasks are still frozen, so request_firmware will
just timeout and fail. So cache firmware image in memory for later
reuse in ->resume method.

On resume card state is likely lost so we have to reload firmware

*Properly get/set all available ISR/IMR values and review common/uncommon bits
*Better handling of per-txq interrupts (we can now resolve what q is generating
each interrupt -this will help in debuging wme later)
*Some minor updates from legacy-hal
*Properly handle RXNOFRM and TXNOFRM interrupt masking (even when we don't set
them on IMR they keep showing up, so we disable them by zeroing AR5K_RXNOFRM
and AR5K_TXNOFRM registers). This doesn't exist on legacy-hal but i've tested
it on various cards and it works fine.

The code needs to be split out and cleaned up, so as a
first step remove the capability, to add it back in a
subsequent patch as a separate function. Also remove the
publically facing return value of the function and the
wiphy argument. A number of internal functions go from
being generic helpers to just being used for alpha2
setting.

The problem fixed here is that iwl3945_mac_get_tsf() returns 0, as the
function is not implemented, and this is considered as a valid value by
the mac layer in mlme.c:1605. The consequence is that the STA in ad-hoc
mode is inserted/removed quite frequently due to IBSS merging.

This patch drops unreadable usage of IWL_SET/GET_BITS16 in byte count
tables handling
This patch also cleans a bit the byte count table code and adds
WARN_ON traps on invalid values

In iwl_bg_request_scan function, if we could not send a
scan command it will go to done.
In done it does the right thing to call mac80211 with
scan complete, but the problem is STATUS_SCAN_HW is still
set causing any future scan to fail. Fix by clearing the scanning status
bits if scan fails.

Wireless HW without any dedicated queues for aggregation
do not need the ampdu_queues mechanism present right now
in mac80211. Since mac80211 is still incomplete wrt TX MQ
changes, do not allow aggregation sessions for drivers that
set ampdu_queues.
This is only an interim hack until Intel fixes the requeue issue.

this enforces the change only when we are asked nicely. When
not asked we simply try to use the max power, we don't tx power
