Marcelo,
Have you tried writing to any other MAC, BBP, RF register? What are the
other registers that you have tried writing?

Hi Ronak,

Is the write operation to the MAC, BBP or RF registers supported?

Apparently it does not work, since the written values are not retained:

-bash-3.1# /home/marcelo/wlanconfig eth0 rdmac 0x0
Driver build with Wireless Extension 21
MAC[0x0000] = 0x0033fa05
-bash-3.1# /home/marcelo/wlanconfig eth0 wrmac 0x0 0xffffffff
Driver build with Wireless Extension 21
Writing[ 2255.598546] 00  MAC Register 0x01 0000 with 0xffff00 ffff
00 00 ff ff ff ff
MAC[0x0000] = 0xffffffff
-bash-3.1# /home/marcelo/wlanconfig eth0 rdmac 0x0
Driver build with Wireless Extension 21
MAC[0x0000] = 0x0033fa05

Any clues are appreciated.
