mac80211: Get rid of search loop for rate group index
Finding the group index for a specific rate is done by looping through
all groups and returning if the correct one is found. This code is
called for each tx'ed frame and thus it makes sense to reduce its
runtime.
Do this by calculating the group index by this formula based on the SGI
and HT40 flags as well as the stream number:
idx = (HT40 * 2 * MINSTREL_MAX_STREAMS) +
(SGI * MINSTREL_MAX_STREAMS) +
(streams - 1)
Hence, the groups are ordered by th HT40 flag first, then by the SGI
flag and afterwards by the number of used streams.
This should reduce the runtime of minstrel_ht_get_group_idx
considerable.

mac80211: remove crypto special case for auth frames
The shared key authentication frame that needs to be
encrypted (the third one in the shared key handshake)
is directly encrypted in ieee80211_send_auth and the
IEEE80211_TX_INTFL_DONT_ENCRYPT is set. All others
are not encrypted, so the only way to get to this is
erroneously on no-monitor AP side.
Remove the special case for authentication frames to
fix the AP shared key side when operating without
cooked monitor interfaces -- with cooked monitor the
IEEE80211_TX_INTFL_DONT_ENCRYPT also gets set, so we
never get here -- an AP never encrypts auth frames.
Without this patch, an AP operating in WEP mode with
my no-monitor patches would erroneously encrypt all
authentication frames, instead of none.

this -- it is also unpredictable since on the BSS
context we might have any parameters, and there it
might even be programmed for HT.
Explicitly program default QoS parameters into the
PAN context for P2P (the defaults are 11g but with
QoS disabled) to make device behaviour predictable.
This also helps when in a follow-up patch we will
use TX QoS parameters from mac80211 only for the
context they were meant for -- without this first
that would completely break P2P device discovery.

The problem with PSM when a hidden SSID was used was originally
reported by Juuso Oikarinen.
- When generally scanning, the AP is getting a bss entry with
a zero SSID.
- When associating, a probe-req is sent to the AP with the SSID,
and as a result a probe-response is received with the hidden
SSID in place. As a consequence, a second bss entry is created
for the AP, now with the real SSID.
- After association, mac80211 executes ieee80211_recalc_ps(),
but does not switch to powersave because the beacon-ies are missing.
As result, the STA does not ever enter PSM.

this by reallocating the headroom instead of dropping the skb
when it has lesser headroom than needed.

ath6kl: Remove few unused WMI stuff
* Removed unused WOW_MAX_FILTER_LISTS macro.
* Removed empty ath6kl_wmi_get_wow_list_event_rx() function.
List of configured WOW patterns are maintained in CFG layer
itself. No need to have this function in ath6kl to get
configured WOW pattern list. It can added later if we need
it for debugging.

ath6kl: Remove WARN_ON msg in Suspend path
In the current code, WOW resume is executed first from RX path
and ar->state is moved to ATH6KL_STATE_ON. When platform calls
ath6kl_sdio_resume() in CFG resume context, that time ar->state
could have moved to ON state. Printing WARN_ON(1) is void in
this context. Hence removing this.
Once WOW resume is removed from RX path, This WARN_ON msg can be
reverted.

ath6kl: Perform WOW resume in RX path in case of SDIO IRQ wake up
The target triggers sdio data line to wake up the host when
WOW pattern matches. This causes sdio irq handler is being
executed in the host side which internally hits ath6kl's RX path.
WOW resume should happen before start processing any data from
the target. So it's required to perform WOW resume in RX path.
This area needs bit rework to avoid WOW resume in RX path,
As of now it's fine to have this model, rework will be done later.
