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.
