+ depends on CSRC_R4K && MIPS32_O32

+ help
+ This optoin enables the Emulated rdtsc support for MIPS, which allows
+ the user-space applications read the R4k count directly. Currently,
+ this only support the CONFIG_MIPS32_O32 and R4K, but future, we may
+ add support for scall64-{n32,64}.S and scall32-32.S and for the count
+ registers provided by the other MIPS variants.
+
+ This emulation based on the syscall instruction, by default, the
+ syscall is encoded as 0x0000000c, except the 0xc, the other parts can
+ be encoded as specific meaning. when a syscall instruction is issued,
+ through checking the encoding of the instruction, when the encoding
+ is the generic 0x000000c, we do the generic syscall work, if
+ something other is encoded in, we can do relevant things, except for
+ the light-weight things, such as read a register. herein, we read the
+ count register whenever there is something encoded in the syscall
+ instruction. In the future, we may be possible to abstract more
+ light-weight & frequently-used operations and add a
+ sys_call_table-like table to store the entries of some light-weight
+ operations and encode 1,2,3... into the syscall instruction and jump
+ to respective entry for diffrent numbers, as a result, we get
+ fast-syscall and which may speed up the user-space applications and
+ even be possibly improve the determinism.

+ #include <stdio.h>

+
+ /*
+ * Currently, our return value is only 32bit, In the long run,

+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts. The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames. With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.

+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.
+- Altought 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.

+
+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).

+rtl8187 Linux kernel driver
+Released under the terms of GNU General Public Licence (GPL)
+Copyright(c) Andrea Merello - 2004,2005
+
+Portions of this driver are based on other projects, please see the notes
+in the source files for detail.
+A special thanks go to Realtek corp for their support and to David Young
+------------------------------------------------------------------------------
+
+This is an attempt to write somethig that can make rtl8187 usb dongle wifi card
+on Linux using only opensource stuff.
+The rtl8225 radio is supported.
+
+It's in early development stage so don't expect too much from it
+(also use it at your own risk!)
+This should be considered just a fragment of code.. using it on your(any)
+system is at your own risk! Please note that I never supported the idea to
+use it in any way, so i cannot be considered responsible in any way for
+anything deriving by it usage.
+
+Anyway for now we have monitor mode and managed mode
+basically working! This isn't necessary stable, but seems to work..
+
+This driver is still under development and very far from perfect. It should work on x86,
+Other archs are untested..
+
+To compile the driver simply run make.
+
+The driver contains also the ieee80211.h and ieee80211_crypt.h from the ieee stack.
+Note that for some reasons this stack is NOT the same that will be included in newer
+2.6 kernel. I will try to port to this stack as soon as it will have enought features
+to support 8187 cards.
+Please note that you will have to make sure the two .h files are the same of the ieee
+stack.
+In other words when you download from the CVS this driver and the ieee80211 stack a good
+idea is to copy the ieee80211.h and ieee80211_crypt.h from the ieee directory to the drv
+directory
+
+Warning during compile are OK
+
+To wake up the nic run:
+
+ ifconfig <ifacename> up
+
+(where <ifacename> is your network device for wlan card).
+
+Please note that the default interface name is wlanX.
+
+Please note thet this will take several seconds..
+
+If you would like to set the interface name to something else you may use the
+'devname=' module parameter. For example:
+
+ insmod r8187.ko ifname=eth%d
+
+will set the interface name of this device to something like eth0.
+
+Once the nic is up it can be put in a monitor mode by running:
+
+ iwconfig <ifacename> mode monitor
+
+and channel number may be changed by running:
+
+ iwconfig <ifacename> channel XX
+
+
+In monitor mode a choice may be made via iwpriv if the nic should pass packets
+with bad crc or drop them.
+
+To put the nic in managed mode run:
+
+ iwconfig <ifacename> mode managed
+
+In managed mode there is support for
+
+ iwlist scan
+
+that should report the currently available networks.
+Please note that in managed mode channels cannot be changed manually.
+
+To associate with a network
+
+ iwconfig <ifacename> essid XXXXX
+
+where XXXXX is the network essid (name) reported by 'iwlist scan'. Please
+note that essid is case sensitive.
+
+If your network is not broadcasting the ESSID, then you need to specify *also*
+the AP MAC address
+
+ iwconfig <ifacename> ap XX:XX:XX:XX:XX:XX
+
+The driver accepts another boolean parameter: hwseqnum
+If set to 1 it lets the card HW take care of the sequence number of the TXed
+frames. Altought in managed mode I can't see an important reason to use HW to
+do that, when we'll start to TX beacons in master (AP) and ad-hoc modes most
+probably it will be extremely useful (since most probably we will use two HW
+queues).
+
+I'm unsure if it will work correctly on all NICs.. reports are *VERY, VERY* apreciated..
+
+
+ WEP
+ ===
+
+WEP encryption should work. For now it's done by host, not by the nic. Key can be set with:
+Key can be set with
+
+ iwconfig <ifacename> key 12345...
+
+WEP is supported via software thanks to the ipw stack.
+
+Shared and open authentication are supported
+
+ IWPRIV
+ ======
+
+This driver supports some private handlers:
+-badcrc: let you choose to kill or to pass to the upper layer frames with bad crc in monitor mode
+-activescan: if 0 the driver will avoid to send probe requests, sanning will be only on beacon basis
+
