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

In done it does the right thing to call mac80211 with

Unfortunately, the result was that mac80211 didn't see all the beacons
it actually wanted to see. This caused lost associations.

*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

The problem fixed here is that iwl3945_mac_get_tsf() returns 0, as the

the mac layer in mlme.c:1605. The consequence is that the STA in ad-hoc

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.
In this driver, I don't simply use netdev_priv() to replace netdev->priv.
The reason is:
Pointer netdev->priv was changed in this driver, but it shouldn't.
Because the memory was allocated when alloc_netdev() and netdev->priv
should always point to that memory.
So I use netdev->ml_priv to replace netdev->priv.
After replacing, both ai and ai->wifidev->ml_priv point to the same memory.

This change adds short slot handling for 8187B variant of rtl8187 chips.
Some things to note about changes done:
* Values used are chosen to met 802.11-2007 spec. This raised a question
about SIFS value used with 8187L: 0x22 (34) doesn't match any spec
value. For now just don't change 8187L, but is something to be
looked at.
* On 8187B, the location of EIFS register is at the same place as BRSR+1
of struct rtl818x_csr. Unfortunately there is no clean way to
accomodate 8187B differences currently, just use address of BRSR+1 and
comment about it. The same thing happens for Ack timeout register,
that is on CARRIER_SENSE_COUNTER location of 8187L. The eifs and ack
timeout values are in units of 4us. All these registers information
was gathered from references being the vendor gpl driver and 8180
datasheet, unfortunately there is no information about this on 8187B
datasheet. Also the ack timeout value was inspired by the same
calculation as done on rt2x00.

The HT handling has the following deficiencies, which I've
(partially) fixed:
* it always uses the AP info even if there is no AP,
hence has no chance of working as an AP
* it pretends to be HW config, but really is per-BSS
* channel sanity checking is left to the drivers
* it generally lets the driver control too much
HT enabling is still wrong with this patch if you have more than
one virtual STA mode interface, but that never happens currently.
Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be
wrong, see the comment in ieee80211_enable_ht().
Additionally, this fixes a number of bugs:
* mac80211: ieee80211_set_disassoc doesn't notify the driver any
more since the refactoring
* iwl-agn-rs: always uses the HT capabilities from the wrong stuff
mac80211 gives it rather than the actual peer STA
* ath9k: a number of bugs resulting from the broken HT API
I'm not entirely happy with putting the HT capabilities into
struct ieee80211_sta as restricted to our own HT TX capabilities,
but I see no cleaner solution for now.

"mac80211 and IEEE80211_CONF_SHORT_SLOT_TIME"
Of course, bss_info_changed provides some more useful data.
e.g.: basic_rates, dtim_period, beacon_int and maybe even more.
Everything can be hooked up if it's necessary.

Use the newly introduced pci_ioremap_bar() function in drivers/net.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.
