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
http://www.ATComputing.nl/cowloop/
