2008 7/18
The RX has can't receive OFDM packet correctly,
Guess it need be do RX calibrate.
before 2008 3/1
1: The RX get too much "CRC failed" pakets, it make the card work very unstable,
2: After running a while, the card will get infinity "RX Frame" and "Error"
interrupt, not know the root reason so far, try to fix it
3: Using two tx queue txd and txm but not only txm.
4: Set the hdr correctly.
5: Try to do recalibrate correvtly
6: To support G mode in future
7: Fix the mac address can't be readed and set correctly in BE machine.
8: Fix include and exclude FCS in promisous mode and manage mode
9: Using sta_notify to notice sta change
10: Turn on frame reception at the end of start
11: Guess the card support HW_MULTICAST_FILTER
12: The tx process should be implment atomic?
13: Using mac80211 function to control the TX&RX LED.

config COWLOOP
tristate "copy-on-write pseudo Block Driver"
depends on BLOCK
default n
---help---
Cowloop is a "copy-on-write" pseudo block driver. It can be
stacked on top of a "real" block driver, and catches all write
operations on their way from the file systems layer above to
the real driver below, effectively shielding the lower driver
from those write accesses. The requests are then diverted to
an ordinary file, located somewhere else (configurable). Later
read requests are checked to see whether they can be serviced
by the "real" block driver below, or must be pulled in from
the diverted location. More information and userspace tools to
use the driver are on the project's website

/*
** COWLOOP block device driver (2.6 kernel compliant)
** =======================================================================
** Read-write loop-driver with copy-on-write functionality.
**
** Synopsis:
**
** modprobe cowloop [maxcows=..] [rdofile=..... cowfile=.... [option=r]]
**
** Definition of number of configured cowdevices:
** maxcows= number of configured cowdevices (default: 16)
** (do not confuse this with MAXCOWS: absolute maximum as compiled)
**
** One pair of filenames can be supplied during insmod/modprobe to open
** the first cowdevice:
** rdofile= read-only file (or filesystem)
** cowfile= storage-space for modified blocks of read-only file(system)
** option=r repair cowfile automatically if it appears to be dirty
**
** Other cowdevices can be activated via the command "cowdev"
** whenever the cowloop-driver is loaded.
**
** The read-only file may be of type 'regular' or 'block-device'.
**
** The cowfile must be of type 'regular'.
** If an existing regular file is used as cowfile, its contents will be
** used again for the current read-only file. When the cowfile has not been
** closed properly during a previous session (i.e. rmmod cowloop), the
** cowloop-driver refuses to open it unless the parameter "option=r" is
** specified.
**
** Layout of cowfile:
**
** +-----------------------------+
** | cow head block | MAPUNIT bytes
** |-----------------------------|
** | | MAPUNIT bytes
** |--- ---|
** | | MAPUNIT bytes
** |--- ---|
** | used-block bitmap | MAPUNIT bytes
** |-----------------------------|
** | gap to align start-offset |
** | to 4K multiple |
** |-----------------------------| <---- start-offset cow blocks
** | |
** | written cow blocks | MAPUNIT bytes
** | ..... |
**
** cowhead block:
** - contains general info about the rdofile which is related
** to this cowfile
**
** used-block bitmap:
** - contains one bit per block with a size of MAPUNIT bytes
** - bit-value '1' = block has been written on cow
** '0' = block unused on cow
** - total bitmap rounded to multiples of MAPUNIT
**

** 200507 Check for free space to expand cowfile. Gerlof Langeveld
** 200902 Upgrade for kernel 2.6.28 Hendrik-Jan Thomassen
**
** Inspired by
** loop.c by Theodore Ts'o and
** cloop.c by Paul `Rusty' Russell & Klaus Knopper.
**
** Design-considerations:
**
** For the first experiments with the cowloop-driver, the request-queue
** made use of the do_generic_file_read() which worked fine except
** in combination with the cloop-driver; that combination
** resulted in a non-interruptible hangup of the system during
** heavy load. Other experiments using the `make_request' interface also
** resulted in unpredictable system hangups (with proper use of spinlocks).
**
** To overcome these problems, the cowloop-driver starts a kernel-thread
** for every active cowdevice.
** All read- and write-request on the read-only file and copy-on-write file
** are handled in the context of that thread.
** A scheme has been designed to wakeup the kernel-thread as
** soon as I/O-requests are available in the request-queue; this thread
** handles the requests one-by-one by calling the proper read- or
** write-function related to the open read-only file or copy-on-write file.
** When all pending requests have been handled, the kernel-thread goes
** back to sleep-state.
** This approach requires some additional context-switches; however the
** performance loss during heavy I/O is less than 3%.
