This patch fixes the issue of slow reconnection to an IBSS cell after
disconnection from it. Now the interface's bssid is reset upon ifdown.
ieee80211_sta_find_ibss:
if (found && memcmp(ifsta->bssid, bssid, ETH_ALEN) != 0 &&
(bss = ieee80211_rx_bss_get(dev, bssid,
local->hw.conf.channel->center_freq,
ifsta->ssid, ifsta->ssid_len)))
Note:
In general disconnection is still not handled properly in mac80211

This patch fixes a deadlock of sta->lock use, occurring while changing
tx aggregation states, as dev_queue_xmit end up in new function
test_and_clear_sta_flags that uses that lock thus leading to deadlock

This patch updates mac80211 and drivers to be multi-queue aware and
use that instead of the internal queue mapping. Also does a number
of cleanups in various pieces of the code that fall out and reduces
internal mac80211 state size.

This patch converts mac80211 and all drivers to have transmit
information and status in skb->cb rather than allocating extra
memory for it and copying all the data around. To make it fit,
a union is used where only data that is necessary for all steps
is kept outside of the union.
A number of fixes were done by Ivo, as well as the rt2x00 part
of this patch.

Having drivers start queues is just confusing, their ->start()
callback can block and do whatever is necessary, so let mac80211
start queues and have drivers wake queues when necessary (to get
packets flowing again right away.)

This patch follows the 11n spec in separation between Tx and Rx MCS
capabilities. Up until now, when configuring the HT possible set of Tx
MCS only Rx MCS were considered, assuming they are the same as the Tx MCS.
This patch fixed this by looking at low level driver Tx capabilities.

trying to clean up the signal/noise code. the previous code in mac80211 had
confusing names for the related variables, did not have much definition of
what units of signal and noise were provided and used implicit mechanisms from
the wireless extensions.
this patch introduces hardware capability flags to let the hardware specify
clearly if it can provide signal and noise level values and which units it can
provide. this also anticipates possible new units like RCPI in the future.
for signal:
IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point
IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW
for noise we currently only have dBm:
IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW
if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.
i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

As discussed earlier, we can unify locking in struct sta_info
and use just a single spinlock protecting all members of the
structure that need protection. Many don't, but one of the
especially bad ones is the 'flags' member that can currently
be clobbered when RX and TX is being processed on different
CPUs at the same time.
Because having four spinlocks for different, mostly exclusive
parts of a single structure is overkill, this patch also kills
the ampdu and mesh plink spinlocks and uses just a single one
for everything. Because none of the spinlocks are nested, this
is safe.
It remains to be seen whether or not we should make the sta
flags use atomic bit operations instead, for now though this
is a safe thing and using atomic operations instead will be
very simple using the new static inline functions this patch
introduces for accessing sta->flags.
Since spin_lock_bh() is used with this lock, there shouldn't
be any contention even if aggregation is enabled at around the
same time as both requires frame transmission/reception which
is in a bh context.

This
* makes the queue number passed to drivers a u16
(as it will be with skb_get_queue_mapping)
* removes the useless queue number defines
* splits hw->queues into hw->queues/ampdu_queues
* removes the debugfs files for per-queue counters
* removes some dead QoS code
* removes the beacon queue configuration for IBSS
so that the drivers now never get a queue number
bigger than (hw->queues + hw->ampdu_queues - 1)
for tx and only in the range 0..hw->queues-1 for
conf_tx.

The error path in ieee80211_register_hw() may call the unregister_netdev()
and right after it - the free_netdev(), which is wrong, since the
unregister releases the device itself.
So the proposed fix is to NULL the local->mdev after unregister is done
and check this before calling free_netdev().
I checked - no code uses the local->mdev after unregister in this error
path (but even if some did this would be a BUG).

This reorders the open code so that WDS peer STA info entries
are added after the corresponding interface is added to the
driver so that driver callbacks aren't invoked out of order.
Also make any master device startup fatal.

When STAs are expired, we need to hold the sta_lock. Using
the same lock for keys too would then mean we'd need another
key free function, and that'll just lead to confusion, so just
use a new spinlock for all key lists.
