[PATCH] mac80211: make ieee802_11_parse_elems return void
Some APs send management frames with junk padding after the last IE.
We already account for a similar problem with some Apple Airport
devices, but at least one device is known to send more than a single
extra byte. The device in question is the Draytek Vigor2900:
http://www.draytek.com.au/products/Vigor2900.php
The junk in question looks like an IE that runs off the end of the
frame. This cause us to return ParseFailed. Since the frame in
question is an association response, this causes us to fail to associate
with this AP.
The return code from ieee802_11_parse_elems is superfluous.
All callers still check for the presence of the specific IEs that
interest them anyway. So, remove the return code so the parse never
"fails".

Some AP equipment "in the wild" services multiple SSIDs using the
same BSSID. This patch changes the key of sta_bss_list to include
the SSID as well as the BSSID and the channel so as to prevent one
SSID from eclipsing another SSID with the same BSSID.

Some AP equipment "in the wild" uses the same BSSID on multiple channels
(particularly "a" vs. "b/g"). This patch changes the key of sta_bss_list
to include both the BSSID and the channel so as to prevent a BSSID on

Adam Baker reported that the prism2 ioctl removal changed behaviour
in that now the selection order was the other way around as before.
New API is planned but not done yet, so for now just use the first
matching channel in any mode as was previous behaviour with an unset
next_mode.

The decryption handlers will skip the frame if the RX_FLAG_DECRYPTED
flag is set, so the early flag setting introduced by Johannes breaks
decryption. To work around this, call the handlers first and then set
the flag.

Problem description by Daniel Drake <dsd@gentoo.org>:
"This sequence of events causes loss of connectivity:
<plug in>
<associate as normal in managed mode>
ifconfig eth7 down
iwconfig eth7 mode monitor
ifconfig eth7 up
ifconfig eth7 down
iwconfig eth7 mode managed
<associate as normal>
At this point you are associated but TX does not work. This is because
the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit."
The problem is caused by ieee80211_if_set_type checking for a non-zero
hard_start_xmit pointer value in order to avoid changing that value for
master devices. The fix is to make that check more explicitly linked to
master devices rather than simply checking if the value has been
previously set.

This patch adds sta_notify callback and removes sta_table_notification
which was not used by any driver.
sta_notify() is essential for drivers that keeps notion of station
internally and need to be notified about removal or addition of a station
to the (I)BSS or assocation to an AP.
This version adds interface id to the parameter list
as suggested by Johannes Berg

This improves radiotap injection by removing the shortcut over TX handlers
that led to BUGS when injecting frames without setting a rate and also
resulted in various other quirks. Now, TX handlers are run but some
information that was present in the radiotap header is used instead of
automatic settings.

This moves the sta_process RX handler to after decryption
so that frames that cannot be decrypted don't influence
statistics, it is likely that they were injected or something
else is totally wrong.
