*
* The mode field is used to find out if a device is broadcast,

* different ways about devices to the rest of the kernel
* so the normal IFF_xxx flags are invalid here. For devices
* which can be any combination of the previously mentioned
* attributes, you can set this on a per device basis by
* installing an up() routine.
*
* The device state field, defines the initial state in which the
* device will come up. In the dn_dev structure, it is the actual
* state.
*
* Things have changed here. I've killed timer1 since it's a user space
* issue for a user space routing deamon to sort out. The kernel does
* not need to be bothered with it.
*
* Timers:
* t2 - Rate limit timer, min time between routing and hello messages
* t3 - Hello timer, send hello messages when it expires
*
* Callbacks:
* up() - Called to initialize device, return value can veto use of
* device with DECnet.
* down() - Called to turn device off when it goes down
* timer3() - Called once for each ifaddr when timer 3 goes off
*

#ifndef _IW_HANDLER_H
#define _IW_HANDLER_H
/************************** DOCUMENTATION **************************/
/*
* Initial driver API (1996 -> onward) :
* -----------------------------------
* The initial API just sends the IOCTL request received from user space
* to the driver (via the driver ioctl handler). The driver has to
* handle all the rest...
*
* The initial API also defines a specific handler in struct net_device
* to handle wireless statistics.
*
* The initial APIs served us well and has proven a reasonably good design.
* However, there is a few shortcommings :
* o No events, everything is a request to the driver.
* o Large ioctl function in driver with gigantic switch statement
* (i.e. spaghetti code).
* o Driver has to mess up with copy_to/from_user, and in many cases
* does it unproperly. Common mistakes are :
* * buffer overflows (no checks or off by one checks)
* * call copy_to/from_user with irq disabled
* o The user space interface is tied to ioctl because of the use
* copy_to/from_user.
*
* New driver API (2002 -> onward) :
* -------------------------------
* The new driver API is just a bunch of standard functions (handlers),
* each handling a specific Wireless Extension. The driver just export
* the list of handler it supports, and those will be called apropriately.
*
* I tried to keep the main advantage of the previous API (simplicity,
* efficiency and light weight), and also I provide a good dose of backward
* compatibility (most structures are the same, driver can use both API
* simultaneously, ...).
* Hopefully, I've also addressed the shortcomming of the initial API.
*
* The advantage of the new API are :
* o Handling of Extensions in driver broken in small contained functions
* o Tighter checks of ioctl before calling the driver
* o Flexible commit strategy (at least, the start of it)
* o Backward compatibility (can be mixed with old API)
* o Driver doesn't have to worry about memory and user-space issues
* The last point is important for the following reasons :
* o You are now able to call the new driver API from any API you
* want (including from within other parts of the kernel).
* o Common mistakes are avoided (buffer overflow, user space copy
* with irq disabled and so on).
*
* The Drawback of the new API are :
* o bloat (especially kernel)
* o need to migrate existing drivers to new API
* My initial testing shows that the new API adds around 3kB to the kernel
* and save between 0 and 5kB from a typical driver.
* Also, as all structures and data types are unchanged, the migration is
* quite straightforward (but tedious).
*
* ---
*
* The new driver API is defined below in this file. User space should
* not be aware of what's happening down there...
*
* A new kernel wrapper is in charge of validating the IOCTLs and calling
* the appropriate driver handler. This is implemented in :
* # net/core/wireless.c
*
* The driver export the list of handlers in :
* # include/linux/netdevice.h (one place)
*
* The new driver API is available for WIRELESS_EXT >= 13.
* Good luck with migration to the new API ;-)
*/
/* ---------------------- THE IMPLEMENTATION ---------------------- */
/*
* Some of the choice I've made are pretty controversials. Defining an
* API is very much weighting compromises. This goes into some of the
* details and the thinking behind the implementation.
*
* Implementation goals :
* --------------------
* The implementation goals were as follow :
* o Obvious : you should not need a PhD to understand what's happening,
* the benefit is easier maintainance.
* o Flexible : it should accommodate a wide variety of driver
* implementations and be as flexible as the old API.
* o Lean : it should be efficient memory wise to minimise the impact
* on kernel footprint.
* o Transparent to user space : the large number of user space
* applications that use Wireless Extensions should not need
* any modifications.
*
* Array of functions versus Struct of functions
* ---------------------------------------------
* 1) Having an array of functions allow the kernel code to access the
* handler in a single lookup, which is much more efficient (think hash
* table here).
* 2) The only drawback is that driver writer may put their handler in
* the wrong slot. This is trivial to test (I set the frequency, the
* bitrate changes). Once the handler is in the proper slot, it will be
* there forever, because the array is only extended at the end.
* 3) Backward/forward compatibility : adding new handler just require
* extending the array, so you can put newer driver in older kernel
* without having to patch the kernel code (and vice versa).
*
* All handler are of the same generic type
* ----------------------------------------
* That's a feature !!!
* 1) Having a generic handler allow to have generic code, which is more
* efficient. If each of the handler was individually typed I would need
* to add a big switch in the kernel (== more bloat). This solution is
* more scalable, adding new Wireless Extensions doesn't add new code.
* 2) You can use the same handler in different slots of the array. For
* hardware, it may be more efficient or logical to handle multiple
* Wireless Extensions with a single function, and the API allow you to
* do that. (An example would be a single record on the card to control
* both bitrate and frequency, the handler would read the old record,
* modify it according to info->cmd and rewrite it).
*
* Functions prototype uses union iwreq_data
* -----------------------------------------
* Some would have prefered functions defined this way :
* static int mydriver_ioctl_setrate(struct net_device *dev,
* long rate, int auto)
* 1) The kernel code doesn't "validate" the content of iwreq_data, and
* can't do it (different hardware may have different notion of what a
* valid frequency is), so we don't pretend that we do it.
* 2) The above form is not extendable. If I want to add a flag (for
* example to distinguish setting max rate and basic rate), I would
* break the prototype. Using iwreq_data is more flexible.
* 3) Also, the above form is not generic (see above).
* 4) I don't expect driver developper using the wrong field of the
* union (Doh !), so static typechecking doesn't add much value.
* 5) Lastly, you can skip the union by doing :
* static int mydriver_ioctl_setrate(struct net_device *dev,
* struct iw_request_info *info,
* struct iw_param *rrq,
* char *extra)
* And then adding the handler in the array like this :
* (iw_handler) mydriver_ioctl_setrate, // SIOCSIWRATE
*
* Using functions and not a registry
* ----------------------------------
* Another implementation option would have been for every instance to
* define a registry (a struct containing all the Wireless Extensions)
* and only have a function to commit the registry to the hardware.
* 1) This approach can be emulated by the current code, but not
* vice versa.
* 2) Some drivers don't keep any configuration in the driver, for them
* adding such a registry would be a significant bloat.
* 3) The code to translate from Wireless Extension to native format is
* needed anyway, so it would not reduce significantely the amount of code.
* 4) The current approach only selectively translate Wireless Extensions
* to native format and only selectively set, whereas the registry approach
* would require to translate all WE and set all parameters for any single
* change.
* 5) For many Wireless Extensions, the GET operation return the current
* dynamic value, not the value that was set.
*
* This header is <net/iw_handler.h>
* ---------------------------------
* 1) This header is kernel space only and should not be exported to
* user space. Headers in "include/linux/" are exported, headers in
* "include/net/" are not.
*
* Mixed 32/64 bit issues
* ----------------------
* The Wireless Extensions are designed to be 64 bit clean, by using only
* datatypes with explicit storage size.
* There are some issues related to kernel and user space using different
* memory model, and in particular 64bit kernel with 32bit user space.
* The problem is related to struct iw_point, that contains a pointer
* that *may* need to be translated.
* This is quite messy. The new API doesn't solve this problem (it can't),
* but is a step in the right direction :
* 1) Meta data about each ioctl is easily available, so we know what type
* of translation is needed.
* 2) The move of data between kernel and user space is only done in a single
* place in the kernel, so adding specific hooks in there is possible.
* 3) In the long term, it allows to move away from using ioctl as the
* user space API.
*
* So many comments and so few code
* --------------------------------
* That's a feature. Comments won't bloat the resulting kernel binary.

Timer resolution MUST BE < 10% of min_schedulable_packet_size/bandwidth
Normal IP packet size ~ 512byte, hence:
0.5Kbyte/1Mbyte/sec = 0.5msec, so that we need 50usec timer for
10Mbit ethernet.
10msec resolution -> <50Kbit/sec.
The result: [34]86 is not good choice for QoS router :-(
The things are not so bad, because we may use artifical
clock evaluated by integration of network data flow
in the most critical places.
Note: we do not use fastgettimeofday.
The reason is that, when it is not the same thing as
gettimeofday, it returns invalid timestamp, which is
not updated, when net_bh is active.
*/

Any clock source returns time intervals, measured in units
close to 1usec. With source CONFIG_NET_SCH_CLK_GETTIMEOFDAY it is precisely
microseconds, otherwise something close but different chosen to minimize
arithmetic cost. Ratio usec/internal untis in form nominator/denominator
may be read from /proc/net/psched.
