Is it possible to receive packets without MAC address filtering?

Hi,

I'm planning to do a SoftMAC project such as the one based on Madwifi. My
platform is based on bcm43xx (Buffalo WLI2-PCI-G54S). I traced the b43
device driver for several days. I found that B43_MACCTL_KEEP_CTL and
B43_MACCTL_BEACPROMISC was set in monitor mode. So, I manually set these two
bits in the driver. However, it doesn't work like iwconfig the device into
monitor mode. I use Wireshark to verify it. I also tried to set
B43_MACCTL_PROMISC bit. It doesn't work either.

How can I receive the packets in station (managed) mode but behave like in
monitor mode? Or can I read the packets through PHY directly? Since I'm not
familiar with hardware and firmware, I'm afraid that I'm wasting time on an
impossible idea. If it is possible, would you please tell me which part of
code I should trace? Thank you!


Jack
