Staging: delete rtl8192su driver

Now that we have a much better driver for this device (rtl8712), delete
this driver as it is no longer needed.

drivers/staging/rtl8192su/TODO

-TODO:
-- merge realteks bugfixes and new features into the driver:
-  - an updated version of this driver can be found here:
-    http://www.getnet.eu/products_GN-621U.html
-  - note:
-    realtek has stripped alomost all comments from the source,
-    so please leave all comments that may help in development in the code.
-- prepare private ieee80211 stack for merge with rtl8187se's version:
-  - remove rtl8192su's specific dead code
-  - cleanup ieee80211.h
-  - move rtl8192su's specific code out from ieee80211.h
-  - abstract rtl819su's specific code
-- switch to use shared "librtl" instead of private ieee80211 stack
-- switch to use LIB80211
-- switch to use MAC80211
-- use kernel coding style
-- checkpatch.pl fixes
-- sparse fixes
-- integrate with drivers/net/wireless/rtl818x
-
-Please send any patches to Greg Kroah-Hartman <greg@kroah.com>.

drivers/staging/rtl8192su/ieee80211/readme

-What this layer should do
-
-- It mantain the old mechanism as alternative, so the
-  ipw2100 driver works with really few changes.
-- Encapsulate / Decapsulate ieee80211 packet
-- Handle fragmentation
-- Optionally provide an alterantive mechanism for netif queue stop/wake,
-  so that the ieee80211 layer will pass one fragment per time instead of
-  one txb struct per time. so the driver can stop the queue in the middle
-  of a packet.
-- Provide two different TX interfaces for cards that can handle management
-  frames on one HW queue, and data on another, and for cards that have only
-  one HW queue  (the latter untested and very, very rough).
-- Optionally provide the logic for handling IBSS/MASTER/MONITOR/BSS modes
-  and for the channel, essid and wap get/set wireless extension requests.
-  so that the driver has only to change channel when the ieee stack tell it.
-- Optionally provide a scanning mechanism so that the driver has not to
-  worry about this, just implement the set channel calback and pass
-  frames to the upper layer
-- Optionally provide the bss client protocol handshaking (just with open
-  authentication)
-- Optionally provide the probe request send mechanism
-- Optionally provide the bss master mode logic to handle association
-  protocol (only open authentication) and probe responses.
-- SW wep encryption (with open authentication)
-- It collects some stats
-- It provides beacons to the card when it ask for them
-
-What this layer doesn't do (yet)
-- Perform shared authentication
-- Have full support for master mode (the AP should loop back in the air
-  frames from an associated client to another. This could be done easily
-  with few lines of code, and it is done in my previous version of the
-  stach, but a table of association must be keept and a disassociation
-  policy must be decided and implemented.
-- Handle cleanly the full ieee 802.11 protocol. In AP mode it never
-  disassociate clients, and it is really prone to always allow access.
-  In bss client mode it is a bit rough with AP deauth and disassoc requests.
-- It has not any entry point to view the collected stats.
-- Although it takes care of the card supported rates in the management frame
-  it sends, support for rate changing on TXed packet is not complete.
-- Give up once associated in bss client mode (it never detect a
-  signal loss condition to disassociate and restart scanning)
-- Provide a mechanism for enabling the TX in monitor mode, so
-  userspace programs can TX raw packets.
-- Provide a mechanism for cards that need that the SW take care of beacon
-  TX completely, in sense that the SW has to enqueue by itself beacons
-  to the card so it TX them (if any...)
-APIs
-
-Callback functions in the original stack has been mantained.
-following has been added (from ieee80211.h)
-
-	/* Softmac-generated frames (mamagement) are TXed via this
-	 * callback if the flag IEEE_SOFTMAC_SINGLE_QUEUE is
-	 * not set. As some cards may have different HW queues that
-	 * one might want to use for data and management frames
-	 * the option to have two callbacks might be useful.
-	 * This fucntion can't sleep.
-	 */
-	int (*softmac_hard_start_xmit)(struct sk_buff *skb,
-			       struct net_device *dev);
-
-	/* used instead of hard_start_xmit (not softmac_hard_start_xmit)
-	 * if the IEEE_SOFTMAC_TX_QUEUE feature is used to TX data
-	 * frames. I the option IEEE_SOFTMAC_SINGLE_QUEUE is also set
-	 * then also management frames are sent via this callback.
-	 * This function can't sleep.
-	 */
-	void (*softmac_data_hard_start_xmit)(struct sk_buff *skb,
-			       struct net_device *dev);
-
-	/* stops the HW queue for DATA frames. Useful to avoid
-	 * waste time to TX data frame when we are reassociating
-	 * This function can sleep.
-	 */
-	void (*data_hard_stop)(struct net_device *dev);
-
-	/* OK this is complementar to data_poll_hard_stop */
-	void (*data_hard_resume)(struct net_device *dev);
-
-	/* ask to the driver to retune the radio .
-	 * This function can sleep. the driver should ensure
-	 * the radio has been swithced before return.
-	 */
-	void (*set_chan)(struct net_device *dev,short ch);
-
-	/* These are not used if the ieee stack takes care of
-	 * scanning (IEEE_SOFTMAC_SCAN feature set).
-	 * In this case only the set_chan is used.
-	 *
-	 * The syncro version is similar to the start_scan but
-	 * does not return until all channels has been scanned.
-	 * this is called in user context and should sleep,
-	 * it is called in a work_queue when swithcing to ad-hoc mode
-	 * or in behalf of iwlist scan when the card is associated
-	 * and root user ask for a scan.
-	 * the fucntion stop_scan should stop both the syncro and
-	 * background scanning and can sleep.
-	 * The fucntion start_scan should initiate the background
-	 * scanning and can't sleep.
-	 */
-	void (*scan_syncro)(struct net_device *dev);
-	void (*start_scan)(struct net_device *dev);
-	void (*stop_scan)(struct net_device *dev);
-
-	/* indicate the driver that the link state is changed
-	 * for example it may indicate the card is associated now.
-	 * Driver might be interested in this to apply RX filter
-	 * rules or simply light the LINK led
-	 */
-	void (*link_change)(struct net_device *dev);
-
-Functions hard_data_[resume/stop] are optional and should not be used
-if the driver decides to uses data+management frames enqueue in a
-single HQ queue (thus using just the softmac_hard_data_start_xmit
-callback).
-
-Function that the driver can use are:
-
-ieee80211_get_beacon             - this is called by the driver when
-                                   the HW needs a beacon.
-ieee80211_softmac_start_protocol - this should normally be called in the
-                                   driver open function
-ieee80211_softmac_stop_protocol  - the opposite of the above
-ieee80211_wake_queue             - this is similar to netif_wake_queue
-ieee80211_reset_queue            - this throw away fragments pending(if any)
-ieee80211_stop_queue             - this is similar to netif_stop_queue
-
-
-known BUGS:
-- When performing syncro scan (possiblily when swithcing to ad-hoc mode
-  and when running iwlist scan when associated) there is still an odd
-  behaviour.. I have not looked in this more accurately (yet).
-
-locking:
-locking is done by means of three structures.
-1- ieee->lock (by means of spin_[un]lock_irq[save/restore]
-2- ieee->wx_sem
-3- ieee->scan_sem
-
-the lock 1 is what protect most of the critical sections in the ieee stack.
-the lock 2 is used to avoid that more than one of the SET wireless extension
-handlers (as well as start/stop protocol function) are running at the same time.
-the lock 1 is used when we need to modify or read the shared data in the wx handlers.
-In other words the lock 2 will prevent one SET action will run across another SET
-action (by make sleep the 2nd one) but allow GET actions, while the lock 1
-make atomic those little shared data access in both GET and SET operation.
-So get operation will be never be delayed really: they will never sleep..
-Furthermore in the top of some SET operations a flag is set before acquiring
-the lock. This is an help to make the previous running SET operation to
-finish faster if needed (just in case the second one will totally undo the
-first, so there is not need to complete the 1st really.. ).
-The background scanning mechaninsm is protected by the lock 1 except for the
-workqueue. this wq is here just to let the set_chan callback sleep (I thinked it
-might be appreciated by USB network card driver developer). In this case the lock 3
-take its turn.
-Thus the stop function needs both the locks.
-Funny in the syncro scan the lock 2 play its role (as both the syncro_scan
-function and the stop scan function are called with this semaphore held).
