f4b5d8d874 wl1271: fix sdio driver name in wl1271_sdio_driver
Our SPI driver is called "wl1271_spi" in the driver information structure.
Let's use the same for SDIO so that things are aligned.

152d530d9e ath9k: remove ah->mask_reg, it's never used properly
ah->mask_reg was used to hold different data throughout the driver.
ath9k_hw_init_interrupt_masks() used it to save the value written to
AR_IMR.  ath9k_hw_set_interrupts() used it to hold the interrupt mask as
defined in enum ath9k_int.  Those masks differ in many bits.

Use ah->imask instead of ah->mask_reg in ath9k_hw_set_interrupts() and
ath9k_hw_updatetxtriglevel().  That's what the code was meant to do.
ah->imask is initialized in ath9k_start(), so we don't need to
initialize it from ah->mask_reg.

Once it's done, ah->mask_reg becomes write-only, so it's replaced with a
local variable in ath9k_hw_init_interrupt_masks().

fa83a21898 mac80211: Fix dropping of unprotected robust multicast frames
When selecting the RX key for group-addressed robust management
frames, we do not actually select any BIP key if the frame is
unprotected (since we cannot find the key index from MMIE). This
results in the drop_unencrypted check in failing to drop the frame. It
is enough to verify that we have a STA entry for the transmitter and
that MFP is enabled for that STA; we do not need to check rx->key
here. This fixes BIP processing for unprotected, group-addressed,
robust management frames.

ecbcd32436 mac80211: Fix BIP to be used only with group-addressed frames
BIP (part of IEEE 802.11w) is only supposed to be used with
group-addressed frames. We ended up picking it as a default mechanism
for every management whenever we did not have a STA entry for the
destination (e.g., for Probe Response to a STA that is not
associated). While the extra MMIE in the end of management frames
should not break frames completed in most cases, there is no point in
doing this. Fix key selection to pick the default management key only
if the frame is sent to multicast/broadcast address and the frame is a
robust management frame.

e69e95dbec mac80211: Send deauth/disassoc prior to dropping STA entry
When management frame protection (IEEE 802.11w) is used, the
deauthentication and disassociation frames must be protected whenever
the encryption keys are configured. We were removing the STA entry and
with it, the keys, just before actually sending out these frames which
meant that the frames went out unprotected. The AP will drop them in
such a case. Fix this by reordering the operations a bit so that
sta_info_destroy_addr() gets called only after
ieee80211_send_deauth_disassoc().

Stack also will tell when disable QoS, this will fix driver when working
with older APs, that do not have QoS implemented.

Patch make "force = true" in iwl_active_qos() assuming we always want
to do with QoS what mac stack wish.

Patch also remove unused qos_cap bits, do not initialize qos_active = 0,
as we have it initialized to zero by kzalloc.

e1b3ec1a2a mac80211: explicitly disable/enable QoS
Add interface to disable/enable QoS (aka WMM or WME). Currently drivers
enable it explicitly when ->conf_tx method is called, and newer disable.
Disabling is needed for some APs, which do not support QoS, such
we should send QoS frames to them.

ecdf94b812 iwlwifi: remove skb_linearize for rx frames
Remove skb_linearize() in the iwlwifi drivers since
mac80211 supports paged rx SKBs now.

e3cf8b3f7b mac80211: support paged rx SKBs
Mac80211 drivers can now pass paged SKBs to mac80211 via
ieee80211_rx{_irqsafe}. The implementation currently use
skb_linearize() in a few places i.e. management frame
handling, software decryption, defragmentation and A-MSDU
process. We will optimize them one by one later.
