mac80211 already filled in the MCS rate info for rx'ed frames but tx'ed
frames that are sent to a monitor interface during the status callback

Add the radiotap fields for MCS info to ieee80211_tx_status_rtap_hdr

Get rid of the ieee80211_tx_status_rtap_hdr struct and instead build the
rtap header dynamically. This makes it easier to extend the rtap header

Add ieee80211_tx_radiotap_len to calculate the expected size of the
rtap header before generating it. Since we can't check if the rtap
header fits into the requested headroom during compile time anymore
add a WARN_ON_ONCE.

Johannes Berg d5294971f1 mac80211: dont orphan TX skb
This was another workaround for truesize "bugs".
The reason we did this was that when we orphaned
the SKB it wouldn't be truesize-checked later.
Now that the check is gone (and we just charge
the former smaller size to the socket) there's
no longer a reason to orphan the skb here.

Keep the skb charged to the socket until it is
really freed (or orphaned in TX status). This
helps flow control and allows us to get at the
socket later for other purposes.

Johannes Berg 72267e5cfe mac80211: dont adjust truesize
There's no need to adjust truesize.

The history of this was that we always ran into
skb_truesize_bug (via skb_truesize_check) which
has since been removed in commit 92a0acce18.
skb_truesize_check() checked that truesize  was
bigger or equal to the actual allocation, which
would trigger in mac80211 due to header adding.
The check no longer exists and we shouldn't be
messing with the truesize anwyay.

Rajkumar Manoharan b6f35301ef mac80211: Send nullfunc frames at lower rate during connection monitor
Recently mac80211 was changed to use nullfunc instead of probe
request for connection monitoring for tx ack status reporting
hardwares. Sometimes in congested network, STA got disconnected
quickly after the association. It was observered that the rate
control was not adopted to environment due to minimal transmission.

As the nullfunc are used for monitoring purpose, these frames should
not be sacrificed for rate control updation. So it is better to send
the monitoring null func frames at minimum rate that could help to
retain the connection.

Johannes Berg 37fbd90800 mac80211: allow out-of-band EOSP notification
iwlwifi has a separate EOSP notification from
the device, and to make use of that properly
it needs to be passed to mac80211. To be able
to mix with tx_status_irqsafe and rx_irqsafe
it also needs to be an "_irqsafe" version in
the sense that it goes through the tasklet,
the actual flag clearing would be IRQ-safe
but doing it directly would cause reordering
issues.

This is needed in the case of a P2P GO going
into an absence period without transmitting
any frames that should be driver-released as
in this case there's no other way to inform
mac80211 that the service period ended. Note
that for drivers that don't use the _irqsafe
functions another version of this function
will be required.

Johannes Berg 40b9640883 mac80211: explicitly notify drivers of frame release
iwlwifi needs to know the number of frames that are
going to be sent to a station while it is asleep so
it can properly handle the uCode blocking of that
station.

Before uAPSD, we got by by telling the device that
a single frame was going to be released whenever we
encountered IEEE80211_TX_CTL_POLL_RESPONSE. With
uAPSD, however, that is no longer possible since
there could be more than a single frame.

To support this model, add a new callback to notify
drivers when frames are going to be released.

Johannes Berg deeaee197b mac80211: reply only once to each PS-poll
If a PS-poll frame is retried (but was received)
there is no way to detect that since it has no
sequence number. As a consequence, the standard
asks us to not react to PS-poll frames until the
response to one made it out (was ACKed or lost).

Implement this by using the WLAN_STA_SP flags to
also indicate a PS-Poll "service period" and the
IEEE80211_TX_STATUS_EOSP flag for the response
packet to indicate the end of the "SP" as usual.

We could use separate flags, but that will most
likely completely confuse drivers, and while the
standard doesn't exclude simultaneously polling
using uAPSD and PS-Poll, doing that seems quite
problematic.

Add uAPSD support to mac80211. This is probably not
possible with all devices, so advertising it with
the cfg80211 flag will be left up to drivers that

Due to my previous patches it is now a fairly
straight-forward extension. Drivers need to have
accurate TX status reporting for the EOSP frame.
For drivers that buffer themselves, the provided

Johannes Berg 4049e09acd mac80211: allow releasing driver-buffered frames
If there are frames for a station buffered in

Since the API will soon also be used for uAPSD
it is easily extensible.

Note that before this change drivers announcing
driver-buffered frames in the TIM bit actually
will respond to a PS-Poll with a potentially
lower priority frame (if there are any frames
buffered in mac80211), after this patch a driver
that hasn't been changed will no longer respond
at all. This only affects ath9k, which will need

Johannes Berg 042ec45337 mac80211: let drivers inform it about per TID buffered frames
For uAPSD implementation, it is necessary to know on
which ACs frames are buffered. mac80211 obviously
knows about the frames it has buffered itself, but
with aggregation many drivers buffer frames. Thus,
mac80211 needs to be informed about this.

For now, since we don't have APSD in any form, this
will unconditionally set the TIM bit for the station
but later with uAPSD only some ACs might cause the
TIM bit to be set.

ath9k is the only driver using this API and I only
modify it in the most basic way, it won't be able
to implement uAPSD with this yet. But it can't do
that anyway since there's no way to selectively
release frames to the peer yet.

Since drivers will buffer frames per TID, let them
inform mac80211 on a per TID basis, mac80211 will
then sort out the AC mapping itself.

Johannes Berg 3b9ce80ce9 cfg80211/mac80211: apply station uAPSD parameters selectively
Currently, when hostapd sets the station as authorized
we also overwrite its uAPSD parameter. This obviously
leads to buggy behaviour (later, with my patches that
actually add uAPSD support). To fix this, only apply
those parameters if they were actually set in nl80211,
and to achieve that add a bitmap of things to apply.

Lorenzo Bianconi 89888e368e mac80211: max_tp_rate2 management of minstrel_ht
I noticed a possible issue in the max_tp_rate2 management of
minstrel_ht. In particular, if we look up just among max_tp_rate2 of
each group it will be possible that the selected rate will not be the
mcs with second maximum throughput. I wrote this simple patch.

Rajkumar Manoharan aad14ceb45 mac80211: Send the management frame at requested rate
Whenever the scan request or tx_mgmt is requesting not to
use CCK rate for managemet frames through
NL80211_ATTR_TX_NO_CCK_RATE attribute, then mac80211 should
select appropriate least non-CCK rate. This could help to
send P2P probes and P2P action frames at non 11b rates
without diabling 11b rates globally.

Rajkumar Manoharan e9f935e3e8 nl80211/cfg80211: Add support to disable CCK rate for management frame
Add a new nl80211 attribute to specify whether to send the management
frames in CCK rate or not. As of now the wpa_supplicant is disabling
CCK rate at P2P init itself. So this patch helps to send P2P probe
request/probe response/action frames being sent at non CCK rate in 2GHz
without disabling 11b rates.

This attribute is used with NL80211_CMD_TRIGGER_SCAN and
NL80211_CMD_FRAME commands to disable CCK rate for management frame
transmission.

TSF can be kept per vif.
Add ieee80211_vif param to set/get/reset_tsf, and move
the debugfs entries to the per-vif directory.

Update all the drivers that implement these callbacks.
