8f20fc2498 [MAC80211]: embed key conf in key, fix driver interface
This patch embeds the struct ieee80211_key_conf into struct ieee80211_key
and thus avoids allocations and having data present twice.

This required some more changes:
 1) The removal of the IEEE80211_KEY_DEFAULT_TX_KEY key flag.
    This flag isn't used by drivers nor should it be since
    we have a set_key_idx() callback. Maybe that callback needs
    to be extended to include the key conf, but only a driver that
    requires it will tell.
 2) The removal of the IEEE80211_KEY_DEFAULT_WEP_ONLY key flag.
    This flag is global, so it shouldn't be passed in the key
    conf structure. Pass it to the function instead.

Also, this patch removes the AID parameter to the set_key() callback
because it is currently unused and the hardware currently cannot know
about the AID anyway. I suspect this was used with some hardware that
actually selected the AID itself, but that functionality was removed.

Additionally, I've removed the ALG_NULL key algorithm since we have
ALG_NONE.

cf966838cd [MAC80211]: use switch statement in tx code
The transmit code needs to set the addresses depending on the
interface type, a likely() for AP/VLAN is quite wrong since
most people will be using STA; convert to a switch statement
to make it look nicer.

53cb670042 [MAC80211]: remove unused ioctls (2)
The ioctls

 * PRISM2_PARAM_STA_ANTENNA_SEL
 * PRISM2_PARAM_TX_POWER_REDUCTION
 * PRISM2_PARAM_DEFAULT_WEP_ONLY

are not used by hostapd or wpa_supplicant.

172589ccdd [NET]: DIV_ROUND_UP cleanup (part two)
Hopefully captured all single statement cases under net/. I'm
not too sure if there is some policy about #includes that are
"guaranteed" (ie., in the current tree) to be available through
some other #included header, so I just added linux/kernel.h to
each changed file that didn't #include it previously.

9b8a74e348 [MAC80211]: Improve sanity checks on injected packets
Michael Wu noticed that the skb length checking is not taken care of enough when
a packet is presented on the Monitor interface for injection.

This patch improves the sanity checking and removes fake offsets placed
into the skb network and transport header.

7e9ed18874 [MAC80211]: improved short preamble handling
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
Affected drivers were updated accordingly.

d5d08def92 [MAC80211]: Add LONG_RETRY flag to ieee80211_tx_control
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.. :(

be8755e180 [MAC80211]: improve locking of sta_info related structures
The sta_info code has some awkward locking which prevents some driver
callbacks from being allowed to sleep. This patch makes the locking more
focused so code that calls driver callbacks are allowed to sleep. It also
converts sta_lock to a rwlock.
