David Woodhouse noticed that under some circumstances the number of slab
allocations kept growing. After looking a bit, this seemed to happen
when you had a management mode interface that was *down*.
The reason for this is that when the device is down, all management
frames get queued to the in-kernel MLME (via ieee80211_sta_rx_mgmt) but
then the sta work is invoked but doesn't run when the netif is down.
When you then bring the interface up, all such frames are freed, but if
you change the mode all of them are lost because the skb queue is
reinitialised as soon as you go back to managed mode. The skb queue is
correctly cleared when the interface is brought down, but the code
doesn't account for the fact that it may be filled while it is not up.
This patch should fix the issue by simply ignoring all interfaces that
are down when going through the RX handlers.

Similarly to CTS protection, whether short preambles are used for 802.11b
transmissions should be a per-subif setting, not device global.
For STAs, this patch makes short preamble handling automatic based on the ERP
IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been
restricted to AP-only subifs.
ieee80211_txrx_data.short_preamble (an unused field) was removed.
Unfortunately, some API changes were required for the following functions:
- ieee80211_generic_frame_duration
- ieee80211_rts_duration
- ieee80211_ctstoself_duration
- ieee80211_rts_get
- ieee80211_ctstoself_get

mac80211 informs the driver what the short and long retry values are through
set_retry_limit(), but when packets are being transmitted it did not inform the
driver which of the 2 retry limits should actually be used.
Instead it sends the actual value, but for drivers that can only set the retry limit
and the register and in the descriptor need to indicate which of the limits should
be used this is not really useful.
This patch will add a IEEE80211_TXCTL_LONG_RETRY_LIMIT flag to the
ieee80211_tx_control structure. By default the short retry limit should be
used but if the flag is set the long retry should be used.
This does not prevent the driver to ignore the request for "no retry" packets,
but at least those will be send out with the short retry limit. But there is no
perfect cure for this problem.. :(

My cheapy D-Link AP behaves strangely w.r.t reassociations.
The following sequence of commands causes me to lose association and to be
unable to regain it:
ifconfig eth8 down
ifconfig eth8 up
iwconfig eth8 essid <x>
This is because mac80211 tries to reassociate, rather than just associate.
My AP replies with an association response (not a reassociation response...)
denying the association with code 12: "Association denied due to reason
outside the scope of this standard"
mac80211 tries this reassociation another 4 times or so before finally giving
up.
I see 2 problems here:
1. bringing the interface down and up again should be resetting interface state
i.e. after the interface is brought down, it should have no memory of if or
where it was previously associated
2. after the first reassociation fails, mac80211 should fall back to
standard association for the next attempt

ieee80211_register_hwmode(), which typically runs 2 or 3 times

Currently, CTS protection is partially implemented twice:
1. via prism2 ioctls, only used by hostapd
2. via STA beacon parsing, recorded in sta.use_protection but never used
(other than printed in debugfs)
Protection control should be implemented on a per-subif basis. For example,
a single physical device may be running a soft AP on one channel, and a STA
on another. The AP interface should use protection based on what hostapd told
it, and the STA interface should use protection based on beacon parsing.
These should operate independantly: one subif using protection should not
influence the other.
To implement this, I moved the use_protection flag into ieee80211_sub_if_data
and removed the device-global cts_protect_erp_frames flag.
I also made the PRISM2_PARAM_CTS_PROTECT_ERP_FRAMES write operation only
available for AP interfaces, to avoid any possibility of the user messing with
the behaviour of a STA.
