[DEV] modify 802.11 header on BCM4329

[Hao Han]

Hi all,

I try to modify 802.11 header of tramsitted packets, especially
management frames such as beacons. When the wireless interface works
in master mode (enabled by new firmware named fw_bcm4329_apsta.bin), I
do monitor beacons on air. However, I cannot find the place through
the driver where these beacons are generated and transmitted. Is that
in firmware?

My goal is to modify the value of some exsiting field and add new
fields in beacon. If anyone has such experience, please let me know.
Any feedback would be extremely appreciated :)

Best,
Hao

Hi Hao,

Your guess is right. bcm4329 has most of the stack functionality in 
firmware.
