iwlagn: unmap cmd queue's tfds as BIDI
If the driver is unloaded while there is still a host command in
flight, its tfd will be freed by iwl_tx_queue_free.
This function is called for both types of queues: Tx queues and cmd
queue. This didn't take in count the fact that in Tx queues, tfds are
mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all
TBs are mapped as BIDI.
Hence, tx_queue_free unmapped the second (and higher) TB of each tfd
in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI.
This means that if a multi TFD is in flight while we unload the
driver (which is quite unlikely but can happen), we will get the
warning below.
This patch fixes this.

iwlagn: warn about buggy fw that doesn't set SEQ_RX_FRAME
The way we check if there is host command that should be reclaimed is
way too complicated. We should have a clear indication from the fw.
The fw is expected to set the SEQ_RX_FRAME bit if the frame was
originated by the fw which indicates to the driver that there is no
host command to free.
Somehow, there seem to have been buggy fw out there, hence the very
old comment.
This code checks if we have still buggy fw out there.

rt2x00: Make use of sta_add/remove callbacks in rt2800
This allows us to assign a WCID to each STA even for STAs without
crypto key.
To achieve this search for an unused WCID in the HW WCID table and
assign it to the according STA. When configuring a pairwise key for this
STA we don't need to write the MAC address and BSSIDX anymore but just
update the crypto related fields in the WCID_ATTR table.
This has two advantages:
1) Setting a new key for an already available STA (PTK rekeying) is
slightly less expensive and should improve performance in situations
where a lot of rekeying happens (e.g. a huge number of stations and/or
a small rekeying interval)
2) The TXWI now gets a WCID assigned for unencrypted frames which will
be reflected in the corresponding tx status report. This should make tx
status reports in unencrypted AP mode more reliable as we can
distinguish between multiple key-less STAs.

mac80211: check if mesh frame is in RMC after decrypt
To check whether a frame is in the RMC, we need access to the mesh
header. This header is encrypted in encrypted data frames, so make this
check after the frame has been decrypted.

mac80211: make ieee80211_send_bar available for drivers
To properly maintain the peer's block ack window, the driver needs to be
able to control the new starting sequence number that is sent along with
the BlockAckReq frame.

cfg80211: hold reg_mutex when updating regulatory
The function wiphy_update_regulatory() uses the static variable
last_request and thus needs to be called with reg_mutex held.
This is the case for all users in reg.c, but the function was
exported for use by wiphy_register(), from where it is called
without the lock being held.
Fix this by making wiphy_update_regulatory() private and introducing
regulatory_update() as a wrapper that acquires and holds the lock.

Unblock the RX BA constraint event from firmware in AP mode as well.
This allows us to stop RX BA sessions when the FW requests it.

wl12xx: don't regulate links when a single STA is connected
When operating as AP track the number of connected stations. When a
single STA is connected don't regulate the PS status of the link.
Since this is the only STA connected, there's no point holding space in
FW for other links. This will speed up communications with a single
connected STA in PSM.
