Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+/************************** 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.
